Description

sensor device

[0001] The present invention relates to a sensor device, and more specifically, to a sensor device that is installed in a specific space and can detect the air condition of the space.

[0002] Typically, the Internet of Things (IoT) is a technology that enables a hyper-connected society by connecting objects equipped with unique IDs, sensors, and communication functions using network communication technology and providing various services based on this.

[0003] In the case of conventional IoT-based technologies, not only home networks that automatically manage home appliances through home automation have become possible, but increasingly intelligent and personalized home IoT services have also become possible. These home IoT services are expanding various service areas, such as control and management, by utilizing various sensors.

[0004] In particular, a smart home is a system that connects and monitors devices such as home appliances, energy (electricity, gas), security, and home entertainment.

[0005] For these smart home systems to be built smoothly, technology that monitors the status of a specific space through various sensor devices installed in that space is essential.

[0006] In relation to a sensor device for monitoring the condition of a specific space as described above, Korean Patent Publication No. 10-2020-0069961 (hereinafter referred to as “Prior Document 1”) discloses an air quality detector.

[0007] Specifically, it discloses a casing body having a bottom and side walls extending upward around the bottom, a first PCB horizontally arranged on the top of the bottom, a temperature and humidity sensor mounted on a lower surface of the first PCB, a second PCB horizontally arranged on the top of the first PCB, a CO2 sensor mounted on the second PCB, etc.

[0008] However, the sensor device of prior art document 1 only considers a structure for improving the accuracy of air quality detection, and has a problem in that it does not have a structure that allows the user to intuitively check the detection status.

[0009] In particular, the sensor device of prior art document 1 has a problem in that it does not consider at all a structure that can improve aesthetics while simplifying the structure for visually displaying the detection status.

[0010] In addition, Korean Patent Publication No. 10-2024-0019906 (hereinafter referred to as “Prior Document 2”) discloses a composite air quality sensor module for a vehicle including a TVOC sensor.

[0011] Specifically, the present invention discloses a case portion that forms an internal space, has an inlet formed to allow outside air to flow into the internal space, and an outlet formed to allow air in the internal space to flow out, a substrate portion installed in the internal space, and a sensor portion that is installed in the substrate portion and measures total volatile organic compounds, CO2, temperature, humidity, and dust concentration contained in air flowing into the internal space.

[0012] However, the sensor device of prior art document 2 has a structure in which the sensor is directly exposed to air flowing intensively in a closed path in order to improve the air quality sensing effect, but there is a problem in that the air flowing into the sensor and the air flowing out are mixed with each other, making it difficult to precisely detect changes in the real-time state of air quality.

[0013] In addition, the sensor device of prior art document 2 has a structure in which various sensors are placed inside a sealed passage to minimize temperature influence due to external factors, but there is a problem in that it is difficult to prevent temperature influence between different sensors.

[0014] As described above, in the case of a sensor device for monitoring the status of a specific space, there are challenges that must be addressed in order to not only appropriately display the detection status, but also to have a more appropriate structure in terms of improving performance and minimizing false detection.

[0015] However, conventional sensor devices have limitations in that they cannot adequately solve these problems.

[0016] The present invention aims to solve the above problems of a sensor device that is installed in a specific space and can detect the air condition of the space.

[0017] Specifically, the present invention aims to provide a sensor device that can achieve uniform and aesthetically enhanced light emission even with a relatively simple structure when transmitting visual information through light emission, thereby further improving usability and design effects.

[0018] In addition, the present invention aims to provide a sensor device that visually displays the detection status of a sensor that detects air conditions, thereby enabling a user to more intuitively and easily determine the detection status.

[0019] In addition, the present invention aims to provide a sensor device that can more appropriately detect air conditions by minimizing the influence between each sensor even when various sensors are placed together.

[0020]

[0022] To achieve the above or other purposes, a sensor device according to one aspect of the present invention is configured to have a structure in which uniform and aesthetically enhanced light is emitted when light is emitted through a light-emitting portion. Specifically, a light-emitting plate is installed on the light-emitting path of the light-emitting portion to have a structure in which light is totally reflected.

[0023] In addition, a sensor device according to one aspect of the present invention is configured to have a structure in which the detection status of air through an air quality sensor unit is visually displayed. Specifically, the sensor device is configured to have a structure in which the detection status of the air quality sensor unit is displayed through the light emission of a light emitting unit.

[0024] In addition, a sensor device according to one aspect of the present invention is configured to have a structure in which the influence of an air quality sensor unit, a temperature and humidity sensor unit, and a carbon dioxide sensor unit on each other is minimized when the sensor unit is placed together in a receiving space. Specifically, the sensor device is configured to have a structure in which the parts in which the air quality sensor unit, the temperature and humidity sensor unit, and the carbon dioxide sensor unit are installed are separated from each other by a partition wall.

[0025] Additionally, a sensor device according to one aspect of the present invention may be formed such that the cover portion includes a lower cover and an upper cover.

[0027] In addition, the sensor device according to one aspect of the present invention can emit light from the light emitting portion to the outside through a spaced space between the outermost end of the upper cover and the lower cover.

[0028] In addition, a sensor device according to one aspect of the present invention may have a portion of the light-emitting plate placed in a space where light from the light-emitting portion is emitted to the outside.

[0029] In addition, a sensor device according to one aspect of the present invention may be formed such that the light-emitting plate portion includes a light-emitting plate wall.

[0030] In addition, a sensor device according to one aspect of the present invention may be formed such that the light-emitting plate portion further includes a light-emitting plate groove.

[0031] In addition, the sensor device according to one aspect of the present invention may have a light-emitting plate portion disposed at a lower portion of a light-emitting portion formed as an inclined surface.

[0032] In addition, the sensor device according to one aspect of the present invention may have six light-emitting units arranged rotationally symmetrically with respect to the center of the plane of the receiving space.

[0033] In addition, in a sensor device according to one aspect of the present invention, a light-emitting plate portion may be formed along a 120° section on a plane toward the outer side from each light-emitting portion.

[0034] In addition, in a sensor device according to one aspect of the present invention, a fastening portion for fastening the lower cover and the upper cover may be placed on an outer side on a plane of the light emitting portion.

[0035] In addition, the sensor device according to one aspect of the present invention may have a fastening portion arranged so as to be offset from the shortest light-emitting path of the light-emitting portion in a plane.

[0036] In addition, a sensor device according to one aspect of the present invention may be structured such that an air quality sensor unit is mounted on one surface of a substrate and a light emitting unit is installed on the other surface.

[0052] FIG. 1 is a perspective view showing a sensor device (1000) according to one embodiment of the present invention. FIG. 2 is an exploded perspective view showing a sensor device (1000) according to one embodiment of the present invention. FIG. 3 is a drawing showing a state in which a first partition wall portion (310), a second partition wall portion (320), and a third partition wall portion (330) are formed in a sensor device (1000) according to one embodiment of the present invention. FIG. 4 is a drawing showing the main components arranged in the receiving space (101) inside the cover portion (100) in the sensor device (1000) according to one embodiment of the present invention.

[0053] A sensor device (1000) according to one embodiment of the present invention includes a cover portion (100), an air quality sensor portion (200), and a first partition wall portion (310).

[0054] The cover part (100) is a part in which a receiving space (101) is formed inside, and the main components of the sensor device (1000) according to the present embodiment can be placed in the receiving space (101) of the cover part (100). This cover part (100) forms the main exterior of the sensor device (1000) according to the present embodiment, and can protect the main components placed in the receiving space (101).

[0055] The air quality sensor unit (200) is installed in the receiving space (101) and is a part in which an air intake port (210) and an air outlet port (220) are formed, respectively. The air quality sensor unit (200) can measure dust contained in the air flowing in through the intake port (210) and then discharge it through the outlet port (220).

[0056] In this case, the air quality sensor unit (200) may include a heater (e.g., circuit resistance), a light emitting body (e.g., infrared LED), and a light receiving body (e.g., photodiode detector) that detects light irradiated from the light emitting body within the air quality sensor body in which an intake port (210) and an outlet port (220) are formed.

[0057] Dust entering through the suction port (210) rises along the rising air current generated by the heater, and light (e.g., infrared) irradiated from the light emitter is scattered by the dust. The light receiver detects this scattered light and outputs it in the form of a pulse waveform.

[0058] The above air quality sensor body may have a portion surrounding the photodiode detector covered with an electromagnetic shielding material (e.g., a metal plate). The processor may measure dust in the air based on the output (e.g., a pulse waveform) of the photodetector.

[0059] The first bulkhead (310) is a part formed inside the cover (100) to separate the intake port (210) and the exhaust port (220) from each other, and can prevent the inflow air and exhaust air of the air quality sensor (200) from mixing with each other.

[0060] When a sensor device (1000) according to the present embodiment is installed in a specific space to detect the air condition of the space, it may be important to detect changes in the air condition that occur in real time in the space.

[0061] To this end, the condition of the air flowing into the air quality sensor unit (200) in real time through the intake port (210) in the space must be detected. However, if some of the air flowing out of the air quality sensor unit (200) flows back into the intake port (210), the change in the real-time air condition of the space may be detected inaccurately.

[0062] Therefore, in order to detect more precise changes in air condition, it may be desirable to separate the intake port (210) and the discharge port (220) from each other through the first partition wall portion (310) in that it is necessary to block the air flowing out of the air quality sensor unit (200) from flowing into the intake port (210).

[0063] In this way, the sensor device (1000) according to one embodiment of the present invention is structured such that the intake port (210) and the exhaust port (220) of the air quality sensor unit (200) are separated from each other by the first partition wall unit (310), so that real-time air condition changes in the space where the sensor device (1000) is installed can be detected more precisely.

[0064] In a sensor device (1000) according to one embodiment of the present invention, an intake port (210) and an outlet port (220) may be formed together on one side of the air quality sensor unit (200). In this case, a first partition wall portion (310) may be formed between the intake port (210) and the outlet port (220).

[0065] That is, as illustrated in FIG. 4, the intake port (210) and the discharge port (220) are formed together on one side of the air quality sensor unit (200), so that both the intake and discharge of air can occur through one side of the air quality sensor unit (200).

[0066] Accordingly, the air flow path flowing into the air quality sensor unit (200) and the air flow path flowing out of the air quality sensor unit (200) can be formed relatively short, so that the detection efficiency of the air quality sensor unit (200) can be improved.

[0067] However, as described above, in order to detect more precise changes in air quality, it is necessary to block air flowing out of the air quality sensor unit (200) from flowing into the intake port (210), and therefore, it may be desirable to form a first partition wall portion (310) between the intake port (210) and the discharge port (220).

[0068] In this way, the sensor device (1000) according to one embodiment of the present invention can effectively separate incoming air and outgoing air while minimizing the air flow path to the air quality sensor unit (200), since the first partition wall portion (310) is formed between the intake port (210) and the discharge port (220) formed together on one side of the air quality sensor unit (200).

[0069] A sensor device (1000) according to one embodiment of the present invention may further include a temperature and humidity sensor unit (400) and a second partition wall unit (320).

[0070] The temperature and humidity sensor unit (400) is installed in the receiving space (101) and can detect the temperature and / or humidity of the air flowing into the receiving space (101) of the cover unit (100).

[0071] In this case, the temperature and humidity sensor unit (400) may be provided as an RTD type, a thermocouple type, an infrared type, an electric resistance type, a capacitance type, etc., but is not necessarily limited thereto and may be formed into various structures and shapes as needed.

[0072] The second bulkhead (320) is a part formed inside the cover part (100) to separate the part where the temperature and humidity sensor part (400) is installed from the rest of the receiving space (101), and when the air quality sensor part (200) and the temperature and humidity sensor part (400) are placed together in the receiving space (101), the influence they have on each other can be minimized.

[0073] In particular, since the temperature and humidity sensor unit (400) may malfunction in sensing when a sensor that causes a temperature rise is adjacent to it, it may be desirable to block heat transfer from other components arranged in the vicinity through the second bulkhead unit (320).

[0074] In this way, the sensor device (1000) according to one embodiment of the present invention is structured so that the part where the temperature and humidity sensor unit (400) is installed is separated from the remaining part of the receiving space (101) by the second partition wall unit (320), so that the air condition of the space where the sensor device (1000) is installed can be detected more appropriately.

[0075] A sensor device (1000) according to one embodiment of the present invention may further include a carbon dioxide sensor unit (500) and a third bulkhead unit (330).

[0076] The carbon dioxide sensor unit (500) is installed in the receiving space (101) and can detect carbon dioxide (CO2) contained in the air flowing into the receiving space (101) of the cover unit (100).

[0077] In this case, the carbon dioxide sensor unit (500) may be an infrared gas sensor (or, a nondispersive infrared sensor (NDIR sensor). The NDIR method is a method of obtaining the concentration of a specific component based on the fact that gaseous substances such as carbon monoxide or carbon dioxide have a specific absorption spectrum for infrared light.

[0078] The NDIR type carbon dioxide sensor unit (500) may include a light irradiator that irradiates infrared rays of a specific frequency band absorbed by carbon dioxide, and a light receiver that receives infrared rays detected without being absorbed by carbon dioxide molecules.

[0079] The third bulkhead (330) is a part formed inside the cover part (100) to separate the part where the carbon dioxide sensor part (500) is installed from the rest of the receiving space (101), and can minimize the influence of various sensors on each other when they are placed together in the receiving space (101).

[0080] In particular, since the sensing of each sensor may be inaccurate when air that has passed through another sensor flows into the carbon dioxide sensor unit (500) or when air measured by the carbon dioxide sensor unit (500) flows into another sensor, it may be desirable to separate the carbon dioxide sensor unit (500) from other components arranged around it through the third bulkhead unit (330).

[0081] In this way, the sensor device (1000) according to one embodiment of the present invention is structured so that the portion where the carbon dioxide sensor unit (500) is installed is separated from the remaining portion of the receiving space (101) by the third partition wall portion (330), so that the air condition of the space where the sensor device (1000) is installed can be detected more appropriately.

[0082] Fig. 5 is a side view showing a sensor device (1000) according to one embodiment of the present invention. Fig. 6 is a cross-sectional view showing a sensor device (1000) according to one embodiment of the present invention. Fig. 7 is a drawing showing the arrangement of a light-emitting unit (700) and a fastening unit (800) in a sensor device (1000) according to one embodiment of the present invention.

[0083] A sensor device (1000) according to one embodiment of the present invention may further include a substrate portion (600) and a light-emitting portion (700).

[0084] The substrate portion (600) is a portion on which the air quality sensor portion (200) is mounted on one surface, and may be provided as a PCB (Printed Circuit Board) including a circuit so that the air quality sensor portion (200) can be electrically installed and operated.

[0085] Meanwhile, the temperature and humidity sensor unit (400) and the carbon dioxide sensor unit (500) can also be mounted on one surface of the substrate unit (600).

[0086] The light-emitting portion (700) is installed on the other side of the substrate portion (600) and is a portion capable of emitting light, and can convey visual information to the user through light emission. In particular, the light-emitting portion (700) can visually display the detection status of the air in a specific space where the sensor device (1000) according to the present embodiment is installed.

[0087] However, since the light-emitting part (700) is configured to generate heat to a certain extent, it may be desirable to install it on the other side of the substrate part (600) rather than on one side of the substrate part (600) where various sensors are mounted, thereby minimizing the heat of the light-emitting part (700) from being transferred to various sensors.

[0088] In addition, since various sensors are mounted on one surface of the substrate (600), there are bound to be restrictions on the placement of the light-emitting portion (700), so it may be desirable to place the light-emitting portion (700) on the other surface of the substrate (600) so that the placement of the light-emitting portion (700) can be made more freely.

[0089] In this way, the sensor device (1000) according to one embodiment of the present invention is structured such that the air quality sensor unit (200) is mounted on one surface of the substrate unit (600) and the light emitting unit (700) is installed on the other surface, so that the air quality sensor unit (200) and the light emitting unit (700) can smoothly perform their functions without interference with each other.

[0090] Meanwhile, light emitted from the light emitting portion (700) is totally reflected by the light emitting plate portion (900) and can be emitted to the outside of the sensor device (1000).

[0091] In a sensor device (1000) according to one embodiment of the present invention, the cover portion (100) may include a lower cover (110) and an upper cover (120).

[0092] The lower cover (110) is a part that covers the lower surface of the receiving space (101) and can support the lower part of the main components placed in the receiving space (101). In this case, the lower cover (110) can be made to allow attachment by magnetic force by including a magnetic material or the like.

[0093] The upper cover (120) covers the side and upper surface of the receiving space (101) and is a part that is connected to the lower cover (110). It can cover the main components mounted on the lower cover (110) and minimize their exposure to the outside.

[0094] In particular, since the upper cover (120) is configured to be detachable from the lower cover (110), it is easier to place the main components in the receiving space (101) when manufacturing the sensor device (1000) according to the present embodiment.

[0095] In addition, when maintenance of the sensor device (1000) according to the present embodiment is required, maintenance of the main components can be performed more easily by separating the upper cover (120) from the lower cover (110) to expose the main components of the receiving space (101).

[0096] In this way, since the sensor device (1000) according to one embodiment of the present invention is formed by including a cover part (100) including a lower cover (110) and an upper cover (120), the manufacturing and maintenance of the sensor device (1000) can be easily accomplished.

[0097] A sensor device (1000) according to one embodiment of the present invention may further include a fastening member (800) that fastens the lower cover (110) and the upper cover (120) to each other. In this case, the fastening member (800) may be arranged on the outer side of the light-emitting member (700) on a plane.

[0098] Specifically, the lower cover (110) and the upper cover (120) can be fastened to each other through a fastening portion (800) so that the lower cover (110) and the upper cover (120), which are separable from each other, can maintain a stable coupled state.

[0099] In this case, the more the number of fastening parts (800), the more stable the lower cover (110) and the upper cover (120) can be in a combined state, but arranging the number of fastening parts (800) too many may be inefficient.

[0100] Therefore, in order to maintain a stable connection state between the lower cover (110) and the upper cover (120) while minimizing the number of fastening parts (800), it may be desirable for the fastening parts (800) to be arranged on the outer side of the cover part (100) on a plane.

[0101] In particular, since it is desirable to install a plurality of light-emitting units (700) that perform the function of transmitting visual information through light emission, the fastening unit (800) may be placed on the outer side of the light-emitting unit (700) so as not to interfere with the plurality of light-emitting units (700).

[0102] In this way, in the sensor device (1000) according to one embodiment of the present invention, since the fastening part (800) that fastens the lower cover (110) and the upper cover (120) is positioned on the outer side of the plane of the light emitting part (700), the fastening state of the lower cover (110) and the upper cover (120) through the fastening part (800) can be maintained more stably.

[0103] In a sensor device (1000) according to one embodiment of the present invention, the fastening portion (800) may be arranged so as to be offset from the shortest light-emitting path of the light-emitting portion (700) on a plane. Here, the shortest light-emitting path of the light-emitting portion (700) may be the shortest path from the light-emitting portion (700) to the outside of the sensor device (1000).

[0104] That is, as illustrated in FIG. 7, the fastening part (800) is not placed on the shortest path from the light emitting part (700) to the outside of the sensor device (1000), but is placed on the space between the light emitting part (700) and the sensor device (1000), so that the fastening part (800) can be placed so as to be out of alignment with the shortest light emitting path of the light emitting part (700) on the plane.

[0105] Accordingly, the light emitted from the light emitting portion (700) is not blocked by the fastening portion (800) along the shortest light emitting path, so that the light emitted from the light emitting portion (700) can be smoothly emitted to the outside of the sensor device (1000).

[0106] In this way, the sensor device (1000) according to one embodiment of the present invention can minimize the light emitted from the light emitting unit (700) from being blocked by the fastening unit (800) because the fastening unit (800) is positioned so as to be offset from the shortest light emitting path of the light emitting unit (700) on a plane.

[0107] In a sensor device (1000) according to one embodiment of the present invention, the upper cover (120) may be installed so that the lowermost end of the outer surface is spaced apart from the lower cover (110) by a certain distance.

[0108] That is, as shown in FIGS. 5 and 6, a certain distance is spaced between the outermost end of the upper cover (120) and the lower cover (110), so that external air can flow into the interior of the sensor device (1000) through this spaced distance.

[0109] Additionally, air inside the sensor device (1000) may leak out through the gap between the outermost part of the upper cover (120) and the lower cover (110).

[0110] In this way, the sensor device (1000) according to one embodiment of the present invention can smoothly allow air to flow into and out of the cover portion (100) since a certain distance is provided between the outermost end of the upper cover (120) and the lower cover (110).

[0111] In a sensor device (1000) according to one embodiment of the present invention, the substrate portion (600) is installed in a plate shape in the receiving space (101), and a portion where the suction port (210) and the discharge port (220) are arranged can be formed to be open along the longitudinal direction.

[0112] That is, as illustrated in FIG. 6, air flowing into the interior of the sensor device (1000) through the space between the outermost end of the upper cover (120) and the lower cover (110) needs to move to the intake port (210) of the air quality sensor unit (200) mounted on one surface of the substrate unit (600).

[0113] Accordingly, the substrate portion (600) of the relevant portion is opened along the longitudinal direction, so that air flowing into the interior of the sensor device (1000) can smoothly move to the intake port (210).

[0114] In addition, the air discharged from the air quality sensor unit (200) needs to move to the outside of the sensor device (1000) through the space between the outermost part of the upper cover (120) and the lower cover (110).

[0115] Accordingly, the substrate portion (600) of the relevant portion is opened along the longitudinal direction, so that air flowing out through the discharge port (220) can smoothly move to the outside of the sensor device (1000).

[0116] Meanwhile, the substrate portion (600) where the temperature and humidity sensor portion (400) and the carbon dioxide sensor portion (500) are positioned is also opened along the longitudinal direction so that air can flow in and out of the corresponding sensors smoothly.

[0117] In this way, the sensor device (1000) according to one embodiment of the present invention is formed so that the portion of the plate-shaped substrate (600) where the suction port (210) and the discharge port (220) are arranged is open along the longitudinal direction, so that air flow in the suction port (210) and the discharge port (220) can be achieved smoothly.

[0118] FIG. 8 and FIG. 9 are drawings showing the light-emitting plate portion (900) in more detail in a sensor device (1000) according to one embodiment of the present invention. FIG. 10 is a cross-sectional view showing the shape of the light-emitting plate portion (900) according to the light-emitting portion (700) in a sensor device (1000) according to one embodiment of the present invention. FIG. 11 is a plan view showing the shape of the light-emitting plate portion (900) according to the light-emitting portion (700) in a sensor device (1000) according to one embodiment of the present invention.

[0119] A sensor device (1000) according to one embodiment of the present invention includes a cover portion (100), an air quality sensor portion (200), a light emitting portion (700), and a light emitting plate portion (900).

[0120] The cover part (100) is a part in which a receiving space (101) is formed inside, and the main components of the sensor device (1000) according to the present embodiment can be placed in the receiving space (101) of the cover part (100).

[0121] The air quality sensor unit (200) is installed in the receiving space (101) and can measure dust in the air flowing into the receiving space (101) of the cover unit (100).

[0122] The light-emitting part (700) is a part that is installed in the receiving space (101) and can emit light, and can convey visual information to the user through light emission.

[0123] The light-emitting plate (900) is installed on the light-emitting path of the light-emitting portion (700) and is a portion that totally reflects light, so that the light emitted from the light-emitting portion (700) can be uniformly and aesthetically emitted to the outside of the sensor device (1000).

[0124] Specifically, when transmitting visual information through the light emitting unit (700), spot light or surface light can provide a softer and more aesthetic feeling to the user than point light.

[0125] In this regard, since it may be disadvantageous in terms of cost or structure to place a light source capable of spot light emission or surface light emission in the sensor device (1000), a structure may be considered in which a light source capable of spot light emission is placed and then light is uniformly spread through precision optics and then emitted to the outside.

[0126] However, in order to place a precision optical structure in a sensor device (1000), there may be spatial constraints to prevent the light emitted from the light emitting portion (700) from exceeding the critical angle, and there are constraints such as a need for a precision processing process, which may increase the overall mold cost.

[0127] Accordingly, the sensor device (1000) according to the present embodiment can be configured to have a light emitting plate (900) that totally reflects the light emitted from the light emitting portion (700) without arranging a separate precision optical structure, thereby allowing the light emitted from the light emitting portion (700) to be uniformly and aesthetically emitted to the outside of the sensor device (1000).

[0128] In particular, the thickness of the entire sensor device (1000) can be minimized through a simpler structural shape of the light-emitting plate (900) replacing the optical structure, design freedom can be secured, and application of an assembly structure that minimizes light loss can be possible.

[0129] In this way, the sensor device (1000) according to one embodiment of the present invention has a structure in which a light-emitting plate (900) is installed on the light-emitting path of the light-emitting portion (700) to totally reflect light, so that the usability and design effect of the sensor device (1000) can be further improved.

[0130] In a sensor device (1000) according to one embodiment of the present invention, the air quality sensor unit (200) may be installed in a first portion on a plane of the receiving space (101). In this case, the light emitting unit (700) may visually display the status of the air quality sensor unit (200).

[0131] That is, the light emitting unit (700) can visually display the detection status of the air in a specific space where the sensor device (1000) according to the present embodiment is installed.

[0132] Accordingly, the user can check various information about the state of the air detected by the sensor device (1000) through the color of the light displayed by the light emitting unit (700), whether it flashes, the flashing interval, the flashing pattern, etc.

[0133] In this way, the sensor device (1000) according to one embodiment of the present invention is configured with a structure in which the detection status of the air quality sensor unit (200) is displayed through the light emission of the light emitting unit (700), so that the user can more intuitively and easily determine the detection status of the sensor device (1000).

[0134] A sensor device (1000) according to one embodiment of the present invention may further include a temperature and humidity sensor unit (400) installed in a second portion on the plane of the receiving space (101) and a carbon dioxide sensor unit (500) installed in a third portion on the plane of the receiving space (101).

[0135] In this case, the first part, the second part and the third part can be separated from each other by a bulkhead.

[0136] That is, the part where the temperature and humidity sensor unit (400) is installed can be separated from the remaining part of the receiving space (101) by the second partition wall unit (320). In addition, the part where the carbon dioxide sensor unit (500) is installed can be structured to be separated from the remaining part of the receiving space (101) by the third partition wall unit (330).

[0137] Accordingly, when various sensors such as an air quality sensor unit (200), a temperature and humidity sensor unit (400), and a carbon dioxide sensor unit (500) are placed together in a receiving space (101), the influence they have on each other can be minimized.

[0138] In this way, the sensor device (1000) according to one embodiment of the present invention has a structure in which the air quality sensor unit (200), the temperature and humidity sensor unit (400), and the carbon dioxide sensor unit (500) are installed in a portion separated from each other by a partition wall, so that the air condition of the space in which the sensor device (1000) is installed can be detected more appropriately.

[0139] In a sensor device (1000) according to one embodiment of the present invention, the cover part (100) includes a lower cover (110) and an upper cover (120), so that the manufacturing and maintenance of the sensor device (1000) can be easily accomplished.

[0140] In a sensor device (1000) according to one embodiment of the present invention, the upper cover (120) is installed so that the lowermost end of the outer surface is spaced apart from the lower cover (110) by a certain distance, so that air can flow smoothly into and out of the cover portion (100).

[0141] In a sensor device (1000) according to one embodiment of the present invention, the light emitting portion (700) can emit light to the outside through a light emitting space (102) between the lowermost end of the outer surface of the upper cover (120) and the lower cover (110).

[0142] As described above, since the lowermost end of the outer surface of the upper cover (120) is installed at a certain distance from the lower cover (110), it may be effective to allow light emitted from the light emitting part (700) disposed inside the cover part (100) to be emitted to the outside through the light emitting space (102) between the lowermost end of the outer surface of the upper cover (120) and the lower cover (110).

[0143] In particular, since the upper cover (120) can be evenly spaced apart from the lower cover (110) at a certain interval along the entire circumference of the outer surface, when light is emitted through this light-emitting space (102), a band-shaped light source can be formed overall.

[0144] In this way, the sensor device (1000) according to one embodiment of the present invention emits light from the light emitting portion (700) to the outside through a space between the outermost end of the upper cover (120) and the lower cover (110), so that light can be emitted to the outside of the cover portion (100) smoothly and aesthetically.

[0145] In a sensor device (1000) according to one embodiment of the present invention, the light-emitting plate portion (900) may be formed in a shape that interferes with a virtual line connecting the light-emitting portion (700) and the light-emitting space (102).

[0146] That is, as illustrated in FIG. 10, a part of the light emitting plate (900) is arranged on a virtual line connecting the light emitting part (700) and the light emitting space (102), so that the light emitted from the light emitting part (700) passes through the light emitting plate (900) to reach the light emitting space (102).

[0147] In this way, the sensor device (1000) according to one embodiment of the present invention can ensure that the light emitted from the light emitting unit (700) passes through the light emitting unit (900) before being emitted to the outside, since a part of the light emitting unit (900) is placed in a space where the light from the light emitting unit (700) is emitted to the outside.

[0148] In a sensor device (1000) according to one embodiment of the present invention, the light emitting portion (700) may be placed on the upper portion of the light emitting plate portion (900). In this case, the light emitting plate portion (900) may include a light emitting plate wall (910) that is formed to protrude upward along the periphery.

[0149] That is, as illustrated in Fig. 10, a light emitting portion (700) is installed on the lower surface of the substrate portion (600), and a light emitting plate portion (900) can be arranged below the substrate portion (600) and the light emitting portion (700). In addition, light can be emitted from the light emitting portion (700) in a downward direction and a lateral direction toward the outer side.

[0150] In this case, in order for the light emitted from the light emitting portion (700) to be effectively guided to the light emitting space (102), it is necessary to place a part of the light emitting plate portion (900) on the light emitting path of the light emitted in a direction other than the light emitting space (102).

[0151] Accordingly, it may be desirable to form a light emitting panel wall (910) that protrudes from the light emitting panel (900) to a height that corresponds to a certain portion of the height of the light emitting unit (700) positioned above the light emitting unit (900) so that light emitted from the light emitting unit (700) in a lateral direction passes through the light emitting panel wall (910).

[0152] In this way, since the sensor device (1000) according to one embodiment of the present invention is formed by including the light emitting plate part (900) and the light emitting plate wall (910), the light emitting plate part (900) can be effectively placed in a space where light from the light emitting part (700) is emitted to the outside.

[0153] In a sensor device (1000) according to one embodiment of the present invention, the light-emitting plate portion (900) may further include a light-emitting plate groove (920) formed by recessing on a virtual line connecting the light-emitting portion (700) and the light-emitting space (102).

[0154] As described above, the light from the point-emitting light-emitting portion (700) can be uniformly emitted by being totally reflected through the light-emitting plate portion (900). However, even in this case of total reflection, the light emitted to the outside along the shortest light-emitting path from the light-emitting portion (700) may cause a hot spot phenomenon to occur to some extent.

[0155] Therefore, as illustrated in Fig. 10, it may be desirable to minimize the occurrence of a hotspot phenomenon in this area by allowing light emitted to the outside along the shortest light emission path from the light emitting portion (700) to be partially diffused and fully scattered in the light emitting plate groove (920).

[0156] In this way, the sensor device (1000) according to one embodiment of the present invention is configured such that the light-emitting plate portion (900) further includes a light-emitting plate groove (920), thereby alleviating the hot spot phenomenon caused by point light emission of the light-emitting plate portion (900).

[0157] In a sensor device (1000) according to one embodiment of the present invention, the light emitting plate portion (900) may have a lower portion of the light emitting portion (700) formed as an inclined surface (901).

[0158] That is, as illustrated in Fig. 10, light emitted downward from the light emitting portion (700) can be totally reflected at the inclined surface (901) of the light emitting plate portion (900) and guided toward the outer side.

[0159] Accordingly, light emitted from the light emitting portion (700) is concentrated into the light emitting space (102), so that light emission to the outside of the sensor device (1000) can be effectively achieved.

[0160] In this way, in the sensor device (1000) according to one embodiment of the present invention, since the light emitting plate portion (900) disposed at the lower portion of the light emitting portion (700) is formed as an inclined surface (901), light emitted downward from the light emitting portion (700) can be guided toward the outer side.

[0161] In a sensor device (1000) according to one embodiment of the present invention, the receiving space (101) may be formed in a circular planar shape. In this case, the light emitting unit (700) may be positioned at six points that are rotationally symmetrical with respect to the center of the plane of the receiving space (101).

[0162] In order to achieve a more uniform visual effect through the point-emitting light-emitting portions (700), it may be advantageous to have a larger number of light-emitting portions (700). However, if the number of light-emitting portions (700) is excessively large, not only may it be disadvantageous in terms of manufacturing costs, but there is also a risk of interference with other components.

[0163] Therefore, it is necessary to design the device so that the emitted light can be emitted evenly without any blind spots while arranging the minimum number of light-emitting parts (700).

[0164] In this regard, since the light emitting part (700) made of LEDs and the like has a maximum efficiency angle of 120°, it may be desirable to place the light emitting part (700) at a rotationally symmetrical point by dividing the circular plane into six equal parts as shown in FIG. 11.

[0165] In this way, the sensor device (1000) according to one embodiment of the present invention has six light-emitting units (700) arranged rotationally symmetrically with respect to the center of the plane of the receiving space (101), so that the number of light-emitting units (700) can be optimized in a state where the light-emitting units (700) emit light at the maximum efficiency angle.

[0166] In a sensor device (1000) according to one embodiment of the present invention, the light emitting portion (900) can be formed along a 120° section on a plane toward the outer side from each light emitting portion (700).

[0167] As described above, since the light emitting plate (900) is configured to totally reflect the light emitted from the light emitting plate (700) until it reaches the light emitting space (102), there may be no need for the light emitting plate (900) to be formed on the inner side of the light emitting plate (700) on a plane.

[0168] In addition, since the light-emitting part (700) made of LEDs and the like has a maximum efficiency angle of 120°, it may be desirable for the flat shape of the light-emitting plate part (900) to be formed in a shape corresponding to this maximum efficiency angle.

[0169] Accordingly, as illustrated in FIG. 11, the light emitting plate portion (900) may be formed along a 120° section on the plane toward the outer side from each light emitting portion (700), and a more efficient structure may be achieved by deleting the remaining portion.

[0170] In this way, in the sensor device (1000) according to one embodiment of the present invention, since the light-emitting plate portion (900) is formed along a 120° section on a plane toward the outer side from each light-emitting portion (700), the arrangement of the light-emitting plate portion (900) can be optimized in a state where the light-emitting portion (700) emits light at the maximum efficiency angle.

[0171] A sensor device (1000) according to one embodiment of the present invention further includes a fastening part (800) that fastens the lower cover (110) and the upper cover (120) to each other, and the fastening part (800) is arranged on the outer side of the light-emitting part (700) on a plane, so that the fastening state of the lower cover (110) and the upper cover (120) through the fastening part (800) can be maintained more stably.

[0172] In a sensor device (1000) according to one embodiment of the present invention, the fastening portion (800) is arranged so as to be offset from the shortest light emitting path of the light emitting portion (700) on a plane, so as to minimize light emitted from the light emitting portion (700) being shielded by the fastening portion (800).

[0173] In particular, as described above, when six light-emitting parts (700) are arranged rotationally symmetrically with respect to the center of the plane of the receiving space (101), and each light-emitting part (700) emits light at a maximum efficiency angle of 120° on the plane, as shown in FIG. 11, a structure in which a fastening part (800) is arranged at a portion where the light-emitting angles of adjacent light-emitting parts (700) overlap may be a structure capable of minimizing the shadow zone.

[0174] A sensor device (1000) according to one embodiment of the present invention further includes a substrate (600) on which an air quality sensor unit (200) is mounted on one surface, and a light emitting unit (700) is installed on the other surface of the substrate (600), so that the air quality sensor unit (200) and the light emitting unit (700) can smoothly perform their functions without interference with each other.
