[0029] See the attached Figure 1-4 As shown, an integrated greenhouse sensor in an embodiment of the present utility model includes an upper shell 6, a lower shell 5, a light intensity detection mechanism for detecting the light intensity of the greenhouse, and an air quality detection mechanism for detecting the air quality of the greenhouse.

[0030] The bottom end of the upper shell 6 is an open structure; the upper end of the lower shell 5 is fixedly installed inside the bottom end of the upper shell 6, and an exhaust passage 16 is formed between the lower shell 5 and the upper shell 6; the light intensity mechanism is arranged on the upper shell 6; and the air quality detection mechanism is arranged on the lower shell 5.

[0031] The light intensity detection mechanism and the air quality detection mechanism enable the greenhouse integrated sensor to have diversified detection functions. It can detect the greenhouse light intensity and greenhouse air quality at the same time. It has good practicality and can reduce the procurement cost of greenhouse detection equipment and reduce the construction workload of greenhouse detection equipment.

[0032] In an embodiment of the utility model, the light intensity detection mechanism includes a top plate 8, an outer heat collecting cover 1, an inner heat retaining cover 2, an insulating foam board 4 and a thermal conductivity sensor 3. The top plate 8 is mounted on the top of the upper shell 6 by screws. The outer heat collecting cover 1 and the inner heat retaining cover 2 are both fixedly mounted on the upper part of the top plate 8. The inner heat retaining cover 2 is located on the inner side of the outer heat collecting cover 1. There is a sealed gap between the inner heat retaining cover 2 and the outer heat collecting cover 1, and the inner heat retaining cover 2 and the outer heat collecting cover 1 are both hemispherical. The interior of the inner heat retaining cover 2 is a sealed space. The insulating foam board 4 is fixedly mounted on the upper part of the top plate 8, and the insulating foam board 4 is located inside the inner heat retaining cover 2. The thermal conductivity sensor 3 is fixedly mounted on the upper part of the insulating foam board 4, and the thermal conductivity sensor 3 is connected to the main control board signal through a signal line, and the main control board is fixedly mounted inside the lower shell 5.

[0033] In order to prevent water leakage between the top plate 8 and the top of the upper shell 6 , a waterproof foam pad 7 is installed between the top plate 8 and the top of the upper shell 6 .

[0034] The air quality detection mechanism includes a base plate 10, a filter cover plate 11, a filter element 12 and an exhaust fan 13. The base plate 10 is fixedly mounted on the bottom of the lower shell 5, and the filter cover plate 11 is embedded on the base plate 10 by screws, and the filter cover plate 11 is a hollow structure. The filter element 12 is fixedly mounted on the inner side of the filter cover plate 11, and the exhaust fan 13 is fixedly mounted inside the lower shell 5, and the air suction part of the exhaust fan 13 is arranged opposite to the filter element 12, and the air outlet part of the exhaust fan 13 is connected with the exhaust channel 16. An air quality detection sensor is installed on the main control board, and the air quality detection sensor is located at the connecting part between the air outlet part of the suction fan 13 and the exhaust channel 16.

[0035] In order to facilitate the connection of other sensors, such as soil sensors, a plurality of interfaces 17 are fixedly installed at the bottom of the base plate 10. The interfaces 17 include at least a soil sensor interface, and the interfaces 17 are electrically connected to the main control board through interface leads.

[0036] In order to ensure that the greenhouse comprehensive sensor is in a horizontal state during installation, a level 9 is embedded in the top wall of the upper shell 6, facilitating the use of the level 9 to check whether the greenhouse comprehensive sensor is in a horizontal state.

[0037] To facilitate the installation of the greenhouse comprehensive sensor in the greenhouse, a U-shaped connecting plate 15 is hinged to the outer side surface of the upper shell 6 by screws. At the same time, a turntable is rotatably installed on the outer side surface of the middle part of the U-shaped connecting plate 15, and a mounting plate 14 is installed on the outer side surface of the turntable by screws. Since the U-shaped connecting plate 15 is hinged to the upper shell 6, the upper shell 6 can adjust its angle. The set turntable enables the mounting plate 14 to rotate relative to the U-shaped connecting plate 1, facilitating the multi-directional adjustment of the angle of the upper shell 6 and easily making the greenhouse comprehensive sensor in a horizontal state.

[0038] As Figure 3 shown, the U-shaped connecting plate 15 can be rotated in the left-right direction, and the upper shell 6 can be rotated in the front-back direction, thereby making the greenhouse comprehensive sensor in a horizontal state.

[0039] The static friction force between the U-shaped connecting plate 15 and the upper shell 6 is greater than the total gravity of the upper shell 6, the lower shell 5, the light intensity detection mechanism for detecting the light intensity in the greenhouse, and the air quality detection mechanism for detecting the air quality in the greenhouse. The static friction force between the mounting plate 14 and the U-shaped connecting plate 1 is greater than the total gravity of the upper shell 6, the lower shell 5, the light intensity detection mechanism for detecting the light intensity in the greenhouse, and the air quality detection mechanism for detecting the air quality in the greenhouse. This can prevent the greenhouse comprehensive sensor from changing its angle automatically during use and affecting its performance.

[0040] To facilitate the fixing and installation of the mounting plate 14 on the greenhouse column with two hose clamps, bayonet openings are separately provided near both ends of the mounting plate 14.

[0041] When the greenhouse comprehensive sensor in an embodiment of the present invention is in use, the mounting plate 14 is fixedly installed on the greenhouse column with two hose clamps to achieve the purpose of installing the greenhouse comprehensive sensor in the greenhouse. Then, the upper shell 6 is adjusted with reference to the level 9 to make the greenhouse comprehensive sensor in a horizontal state.

[0042] Light passes through the outer heat collecting cover 1 and the inner heat retaining cover 2 and directly irradiates the front surface of the heat conduction sensor 3. The generated heat radiation is retained inside the hemispherical region by the outer heat collecting cover 1 and the inner heat retaining cover 2, heating the temperature of the front surface of the heat conduction sensor 3, causing the temperature of the thermosensitive sensing component on the back surface of the heat conduction sensor 3 to change, and being transmitted to the main control board installed in the lower shell 5 through a signal line, thereby obtaining the light intensity change data.

[0043] The air in the greenhouse passes through the filter cover 11 and the filter 12 to filter large dust particles, and is sucked into the exhaust duct 16 by the suction fan 13 and discharged. During the discharge process, the sucked air contacts the air quality detection sensor installed on the main control board, and the air quality detection sensor obtains various air indicators;

[0044] When detecting soil parameters, the soil sensor is connected to the corresponding interface 17 on the bottom plate 10, and connected to the main control board fixed to the lower shell 5 through the interface lead, and the signal is transmitted to the main control board or soil related parameters;

[0045] The soil sensor includes at least a pH sensor, a temperature sensor, a humidity sensor, a nitrogen sensor and a potassium ammonium sensor.

[0046] Air quality detection sensors include at least temperature, humidity, air pressure, light, PM2.5, PM10, TVOC, oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), and formaldehyde (CH2O) sensors.

[0047] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
