To meet waterproofing requirements, additional structures such as sealing caps and waterproof rings must be added. Furthermore, to meet safety regulations, the controlled device may require specialized electronic components, such as isolated power supplies. All of this significantly increases the cost of the controlled device. Summary of the Invention

[0016] (3) In one embodiment of the present invention, the number of Hall sensors in the dial encoder can be odd or even, and the number of Hall sensors can be increased or decreased according to actual needs.

Other terms used to describe the relationship between components or layers should be interpreted in the same manner. For ease of understanding, the same components in the following embodiments are indicated by the same symbols.

[0028] Please see Figure 1 This is a schematic diagram of the structure of a Hall sensor-based dial encoder according to the first embodiment of the present invention. As shown in the figure, the dial encoder 1 includes a sensing module 11, a dial module 12, a processing module 13, and a circuit board 14.

[0029] The sensing module 11 is disposed on the circuit board 14 and includes six Hall sensors H1 to H6. In this embodiment, the number of Hall sensors H1 to H6 is even. In another embodiment, the number of Hall sensors H1 to H6 is also odd. In yet another embodiment, the number of Hall sensors can be 3, 4, 5, 7, 8, 9 or more, which can be adjusted according to actual needs.

[0030] The dial module 12 includes six magnets M1 to M6, each corresponding to one of the six Hall sensors H1 to H6. Magnet M1 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H1. Magnet M2 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H2. Magnet M3 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H3. Magnet M4 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H4. Magnet M5 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H5. Magnet M6 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H6. In this embodiment, the first magnetic pole P1 is the S pole, and the second magnetic pole P2 is the N pole. In another embodiment, the first magnetic pole P1 is the N pole, and the second magnetic pole P2 is the S pole.

[0031] The processing module 13 is disposed on the circuit board 14 and electrically connected to the sensing module 11 (Hall sensors H1~H6). In one embodiment, the processing module 13 is a microcontroller (MCU). In another embodiment, the processing module 13 may also be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other similar components.

[0032] The distance between the first magnetic pole of any magnet and the corresponding Hall sensor is adjustable. For example, magnet M1 can be moved closer to Hall sensor H1, shortening the distance between the first magnetic pole P1 of magnet M1 and Hall sensor H1. Similarly, magnet M1 can be moved away from Hall sensor H1, increasing the distance between the first magnetic pole P1 of magnet M1 and Hall sensor H1. Magnets M2 through M6 can also be operated in the same way.

[0033] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the Hall sensor-based dial encoder 1 according to this embodiment should still be included within the patent scope of the invention.

[0034] Please see Figure 2 and Figure 3 . Figure 2 This is a schematic diagram of the connection structure between the processing module and the sensing module of the Hall sensor-based finger encoder according to the first embodiment of the present invention. Figure 3This is a schematic diagram of the operation of the Hall sensor-based dial encoder according to the first embodiment of the present invention. As shown in the figure, Hall sensors H1~H6 are connected to the operating voltage source Vcc on the circuit board 14, and the processing module 13 has input / output ports I / O1~I / O6, which are respectively connected to Hall sensors H1~H6.

[0035] The user can move magnet M1 closer to Hall sensor H1, thus shortening the distance between the first magnetic pole P1 of magnet M1 and Hall sensor H1. When the magnetic induction intensity applied to Hall sensor H1 exceeds its operating point (BOP), Hall sensor H1 outputs a first signal S1 to processing module 13, which is then detected by the input / output port I / O1 of the processing module. Similarly, the user can move magnet M3 closer to Hall sensor H3, thus shortening the distance between the first magnetic pole P1 of magnet M3 and Hall sensor H1. When the magnetic induction intensity applied to Hall sensor H3 exceeds its operating point, Hall sensor H3 outputs a first signal S1 to processing module 13, which is then detected by the input / output port I / O3 of the processing module.

[0036] Since the user did not move Hall sensor M2, when the magnetic field strength applied to Hall sensor M2 is less than the release point (BRP) of Hall sensor M2, it outputs a second signal S2 to processing module 13, causing the input / output port I / O2 of processing module to detect the second signal S2. Similarly, since the user did not move Hall sensors M4-M6, the input / output ports I / O4-I / O6 of processing module all detect the second signal S2. In this embodiment, the first signal S1 is a high-level signal, and the second signal S2 is a low-level signal. In another embodiment, the first signal S1 is a low-level signal, and the second signal S2 is a high-level signal.

[0037] Thus, the finger encoder 1 can generate a binary encoded signal (101000).

[0038] Similarly, if the user moves Hall sensors M1, M4 and M6, the dial encoder 1 can generate a binary encoded signal (100101).

[0039] Similarly, if the user moves Hall sensors M2, M4, M5 and M6, the finger encoder 1 can generate a binary encoded signal (010111).

[0040] Through the above structural design, the finger encoder 1 can generate binary encoded signals through the above-mentioned multiple Hall sensors H1~H6 to realize various applications, such as networking, identifier setting, parameter adjustment or other functions.

[0041] Furthermore, in this embodiment, the number of Hall sensors in the DIP encoder 1 can be odd or even, and the number of Hall sensors can be increased or decreased according to actual needs. Therefore, the DIP encoder 1 can generate different binary encoded signals, enabling it to meet the needs of different applications. Consequently, the DIP encoder 1 has a wider range of applications and is more flexible in its use.

[0042] Furthermore, in this embodiment, the dial encoder 1 can be applied to various controlled devices, such as lighting devices, temperature sensors, humidity sensors, brightness sensors, microwave sensors, infrared sensors, or various IoT devices. Therefore, the dial encoder 1 can assist in realizing various intelligent functions for application in various intelligent systems, such as smart homes, smart parking lots, and smart factories. Thus, the dial encoder 1 aligns with future development trends.

[0043] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the Hall sensor-based dial encoder 1 according to this embodiment should still be included within the patent scope of the invention.

[0044] It is worth mentioning that existing finger encoders, when installed on controlled devices (such as lighting devices, temperature sensors, humidity sensors, brightness sensors, microwave sensors, infrared sensors, etc.), require openings in the housing of the controlled device. This compromises the integrity of the housing and affects the sealing performance of the controlled device. To ensure the controlled device meets waterproof requirements, additional structures such as sealing covers and waterproof rings must be added. Furthermore, to meet safety regulations, the controlled device may require special electronic components, such as isolated power supplies. This significantly increases the cost of the controlled device. In contrast, according to an embodiment of the present invention, the finger encoder includes a sensing module, a finger module, and a processing module. The sensing module includes multiple Hall sensors. The finger module includes multiple magnets corresponding to the Hall sensors. Each magnet has a first magnetic pole and a second magnetic pole, with the first magnetic pole facing the corresponding Hall sensor. The processing module is electrically connected to the sensing module. The distance between the first magnetic pole of any magnet and the corresponding Hall sensor is adjustable. The distance between the first magnetic pole of any magnet and the corresponding Hall sensor is related to the magnetic induction intensity applied to the Hall sensor. Each Hall sensor outputs a first signal to the processing module when the magnetic flux density applied to it exceeds its operating point. Conversely, each Hall sensor outputs a second signal to the processing module when the magnetic flux density applied to it is less than its release point. Through this structural design, the digit encoder can generate a binary coded signal using multiple Hall sensors to achieve various applications.

[0045] Furthermore, according to an embodiment of the present invention, when the finger encoder is mounted on a controlled device, the finger module can be fixed to a first surface of the housing of the controlled device, while the sensing module can be disposed on a second surface adjacent to the housing; the first and second surfaces are opposite to each other. Thus, the finger encoder can be mounted on the housing of the controlled device without the need for openings, and the controlled device does not require additional structures or special electronic components, thus potentially meeting waterproof and safety requirements. Therefore, the cost of the controlled device can be significantly reduced, better meeting the needs of practical applications.

[0046] Furthermore, according to embodiments of the present invention, the number of Hall sensors in the dial encoder can be odd or even, and the number of Hall sensors can be increased or decreased according to actual needs. Therefore, the dial encoder can generate different binary encoded signals, enabling it to meet the needs of different applications. Thus, the dial encoder has a wider range of applications and greater flexibility in use.

[0047] Furthermore, according to embodiments of the present invention, the finger encoder can be applied to various controlled devices, such as lighting devices, temperature sensors, humidity sensors, brightness sensors, microwave sensors, infrared sensors, or various Internet of Things (IoT) devices. Therefore, the finger encoder can assist in realizing various intelligent functions for application in various intelligent systems, such as smart homes, smart parking lots, and smart factories. Thus, the finger encoder aligns with future development trends.

[0048] Furthermore, according to embodiments of the present invention, the design of the dial encoder is simple, significantly reducing hardware complexity and production costs. In addition, the dial encoder is reliable and effectively achieves the desired function. Therefore, the practicality of the dial encoder can be greatly improved to meet market demands. As can be seen from the above, the Hall sensor-based dial encoder according to embodiments of the present invention can indeed achieve excellent technical results.

[0049] Please see Figure 4 This is a schematic diagram of a Hall sensor-based dial encoder installed on a controlled device according to the second embodiment of the present invention. As shown in the figure, the sensing module 11 is disposed on the circuit board 14 and includes five Hall sensors H1 to H5.

[0050] The dial module 12 includes five magnets M1 to M5, each corresponding to one of the five Hall sensors H1 to H5. Magnet M1 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H1. Magnet M2 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H2. Magnet M3 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H3. Magnet M4 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H4. Magnet M5 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H5.

[0051] The processing module 13 is mounted on the circuit board 14 and is electrically connected to the sensing module 11 (Hall sensors H1~H5).

[0052] The controlled device in this embodiment is a lamp tube (lighting device). The dial encoder 1 can be mounted on the lamp head of the lamp tube, and it can be a plastic housing CS. The dial module 12 is fixed to the first surface F1 of the housing CS, while the sensing module 11 and circuit board 14 are both disposed inside the housing CS. Thus, the sensing module 11 can be disposed adjacent to the second surface F2 of the housing CS. The first surface F1 and the second surface F2 are two opposing surfaces.

[0053] In this embodiment, the dial module 12 also includes a housing HG, which has five grooves SR. Five magnets M1 to M5, which can be spherical magnets, are respectively disposed within the five grooves SR. Each groove SR has a limiting element LP (e.g., a protrusion, spring, etc.) at its top and bottom. For example, the user can move magnet M1 towards the Hall sensor H1, shortening the distance between the first magnetic pole P1 of magnet M1 and the Hall sensor H1. When magnet M1 reaches the bottom of the groove SR, the limiting element LP can fix its position. At this time, the Hall sensor H1 can output a first signal S1 to the processing module 13, causing the input / output port I / O1 of the processing module to detect the first signal S1. Similarly, the user can move magnet M1 away from the Hall sensor H1, increasing the distance between the first magnetic pole P1 of magnet M1 and the Hall sensor H1. When magnet M1 moves to the top of slide SR, the limiting member LP can fix the position of magnet M1. At this time, Hall sensor H1 can output a second signal S2 to processing module 13, so that the input / output port I / O1 of the processing module detects the second signal S2. The user can operate magnets M2 to M5 in the same way.

[0054] With the above structural design, the controlled device's housing HG can be fitted with the finger encoder 1 without requiring openings. Therefore, the controlled device does not need additional structures or special electronic components and may meet waterproof and safety requirements. Consequently, the cost of the controlled device can be significantly reduced, making it more suitable for practical applications.

[0055] In another embodiment, the controlled device may also be a temperature sensor, humidity sensor, brightness sensor, microwave sensor, infrared sensor, or various Internet of Things devices.

[0056] The structure of the dial module 12 in this embodiment is only for illustrative purposes. The structure of the dial module 12 can be designed according to actual needs and is not limited to the structure of the dial module 12 in this embodiment.

[0057] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the Hall sensor-based dial encoder 1 according to this embodiment should still be included within the patent scope of the invention.

[0058] Please see Figure 5 This is a schematic diagram of a Hall sensor-based dial encoder installed on a controlled device according to the third embodiment of the present invention. As shown in the figure, the sensing module 11 is disposed on the circuit board 14 and includes five Hall sensors H1 to H5.

[0059] The dial module 12 includes five magnets M1 to M5, each corresponding to one of the five Hall sensors H1 to H5. Magnet M1 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H1. Magnet M2 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H2. Magnet M3 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H3. Magnet M4 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H4. Magnet M5 has a first magnetic pole P1 and a second magnetic pole P2, with the first magnetic pole P1 facing the corresponding Hall sensor H5.

[0060] The processing module 13 is mounted on the circuit board 14 and is electrically connected to the sensing module 11 (Hall sensors H1~H5).

[0061] The controlled device in this embodiment is a lamp tube (lighting device). The dial encoder 1 can be mounted on the lamp head of the lamp tube, and it can be a plastic housing CS. The dial module 12 is fixed to the first surface F1 of the housing CS, while the sensing module 11 and circuit board 14 are both disposed inside the housing CS. Thus, the sensing module 11 can be disposed adjacent to the second surface F2 of the housing CS. The first surface F1 and the second surface F2 are two opposing surfaces.

[0062] In this embodiment, the toggle module 12 includes five button structures, each corresponding to one of the five magnets M1 to M5. Each button structure includes a button body BD and a spring FS. The five magnets M1 to M5 can be respectively disposed within the five button bodies BD. For example, the user can press the button body BD, causing the magnet M1 to move towards the Hall sensor H1, thus shortening the distance between the first magnetic pole P1 of the magnet M1 and the Hall sensor H1. When the spring FS is compressed to a certain extent, the magnet M1 will be very close to the first surface F1. At this time, the Hall sensor H1 can output a first signal S1 to the processing module 13, so that the input / output port I / O1 of the processing module detects the first signal S1. Similarly, the user can release the button body BD, and the spring force of the spring FS will cause the magnet M1 to return to its original position, increasing the distance between the first magnetic pole P1 of the magnet M1 and the Hall sensor H1. At this time, Hall sensor H1 can output a second signal S2 to processing module 13, so that the input / output port I / O1 of the processing module detects the second signal S2. The user can operate magnets M2~M5 in the same way.

[0063] With the above structural design, the controlled device's housing HG can be fitted with the finger encoder 1 without requiring openings. Therefore, the controlled device does not need additional structures or special electronic components and may meet waterproof and safety requirements. Consequently, the cost of the controlled device can be significantly reduced, making it more suitable for practical applications.

[0064] In another embodiment, the controlled device may also be a temperature sensor, humidity sensor, brightness sensor, microwave sensor, infrared sensor, or various Internet of Things devices.

[0065] The structure of the dial module 12 in this embodiment is only for illustrative purposes. The structure of the dial module 12 can be designed according to actual needs and is not limited to the structure of the dial module 12 in this embodiment.

[0066] Through the aforementioned structural design, the DIP encoder 1 can generate corresponding binary encoded signals using multiple Hall sensors H1~H5. These Hall sensors H1~H5 sense changes in the magnetic field based on the position changes of magnets M1~M5 and convert these changes into corresponding electrical signals, thus forming a stable and recognizable binary code. In this way, the DIP encoder 1 can be flexibly applied to various scenarios. For example, the DIP encoder 1 can be used as a tool for setting network addresses or node numbers, or as an identification code for different devices or components in specific functional modules. In addition, it can also be used for parameter adjustment, such as mode selection and function switching, and can even work with other components to achieve related control functions.

[0067] Furthermore, in this embodiment, the number of Hall sensors configured in the DIP encoder 1 is not limited; it can be either odd or even, and the specific number can be increased or decreased according to actual application requirements. This design flexibility allows the DIP encoder 1 to generate corresponding binary encoded signals, thereby supporting more diverse application scenarios. For example, if more status outputs are required, the number of Hall sensors can be increased; if only simple setting or selection functions are needed, the number of Hall sensors can be reduced to lower costs and complexity. Thus, the flexibility of the DIP encoder 1 in product integration can be effectively improved, making its application in different fields more widespread. Therefore, the DIP encoder 1 can effectively meet various diverse application needs, improve the flexibility and efficiency of the overall system design, and further enhance its practical value and competitiveness in the market.

[0068] Furthermore, in this embodiment, the dial encoder 1 possesses excellent compatibility and application flexibility, and can be widely used in various types of controlled devices, including but not limited to lighting devices, temperature sensors, humidity sensors, brightness sensors, microwave sensors, infrared sensors, and various IoT devices. These devices typically require a simple and reliable way to set parameters, switch modes, or identify configurations. The dial encoder 1, through its unique structure and Hall effect sensing technology, can provide stable digital output signals, effectively assisting these devices in achieving individual or overall intelligent functions. By combining with the aforementioned sensing devices or systems, the dial encoder 1 can be used to set the device's operating status, identify addresses, or perform function switching, thereby realizing intelligent applications such as automatic lighting adjustment, real-time response to environmental monitoring data, and energy consumption control optimization. Furthermore, the dial encoder 1 can also be applied to larger-scale intelligent system deployments, such as multi-device linkage control in smart home systems, parking space management and identification in smart parking lots, or zone identification and operating parameter setting of production equipment in smart factories. Therefore, the dial encoder 1 not only meets the technical requirements of today's diverse applications but also has the potential to support the development of future intelligent systems, fully aligning with the trends of the Internet of Things and intelligent devices.

[0069] Furthermore, in this embodiment, the DIP encoder 1 adopts a simplified structural design, effectively reducing the overall hardware complexity and thus significantly reducing material costs and production difficulties during the manufacturing process. Moreover, the DIP encoder 1 exhibits stable performance in terms of functionality, accurately and reliably outputting the required encoded signals to achieve the intended purpose. The DIP encoder 1 not only provides stable and efficient functionality, but its simple and easy-to-manufacture design further enhances the product's practical value and market competitiveness, making it meet market demands.

[0070] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the Hall sensor-based dial encoder 1 according to this embodiment should still be included within the patent scope of the invention.

[0071] In summary, according to embodiments of the present invention, the finger encoder includes a sensing module, a finger module, and a processing module. The sensing module includes multiple Hall sensors. The finger module includes multiple magnets, each corresponding to one of the Hall sensors. Each magnet has a first magnetic pole and a second magnetic pole, with the first magnetic pole facing the corresponding Hall sensor. The processing module is electrically connected to the sensing module. The distance between the first magnetic pole of any magnet and the corresponding Hall sensor is adjustable. The distance between the first magnetic pole of any magnet and the corresponding Hall sensor is related to the magnetic flux density applied to the Hall sensor. Any Hall sensor outputs a first signal to the processing module when the magnetic flux density applied to it is greater than the Hall sensor's operating point. Any Hall sensor outputs a second signal to the processing module when the magnetic flux density applied to it is less than the Hall sensor's release point. Through the above structural design, the finger encoder can generate a binary coded signal through the multiple Hall sensors to achieve various applications.

[0072] Furthermore, according to an embodiment of the present invention, when the finger encoder is mounted on a controlled device, the finger module can be fixed to a first surface of the housing of the controlled device, while the sensing module can be disposed on a second surface adjacent to the housing; the first and second surfaces are opposite to each other. Thus, the finger encoder can be mounted on the housing of the controlled device without the need for openings, and the controlled device does not require additional structures or special electronic components, thus potentially meeting waterproof and safety requirements. Therefore, the cost of the controlled device can be significantly reduced, better meeting the needs of practical applications.

[0073] Furthermore, according to embodiments of the present invention, the number of Hall sensors in the dial encoder can be odd or even, and the number of Hall sensors can be increased or decreased according to actual needs. Therefore, the dial encoder can generate different binary encoded signals, enabling it to meet the needs of different applications. Thus, the dial encoder has a wider range of applications and greater flexibility in use.

[0074] Furthermore, according to embodiments of the present invention, the finger encoder can be applied to various controlled devices, such as lighting devices, temperature sensors, humidity sensors, brightness sensors, microwave sensors, infrared sensors, or various Internet of Things (IoT) devices. Therefore, the finger encoder can assist in realizing various intelligent functions for application in various intelligent systems, such as smart homes, smart parking lots, and smart factories. Thus, the finger encoder aligns with future development trends.

[0075] Furthermore, according to embodiments of the present invention, the design of the finger encoder is simple, significantly reducing hardware complexity and production costs. In addition, the finger encoder is reliable and consistently achieves the desired functionality. Therefore, the practicality of the finger encoder can be greatly improved to meet market demands.
