[0002] Currently, with the continuous concentration of urban population, the daily consumption of vegetables is very large. At the same time, the demand for medicinal herbs and other plants is also relatively large. Therefore, in order to ensure normal supply, indoor plant cultivation is becoming more and more common. As CO2 is an essential condition for plants to carry out photosynthesis, its concentration has a great impact on the growth rate of plants. Therefore, it is necessary to monitor the indoor CO2 concentration in a timely manner during indoor cultivation in order to regulate the indoor CO2 concentration.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0029] Reference Figure 1-6 This utility model provides a sensor housing 100. The sidewalls of the sensor housing 100 are provided with strip-shaped ventilation holes. Specifically, the ventilation holes include a row of first ventilation holes 111 on the front (upper) side of the sensor housing 100, a row of second ventilation holes 114 on the back (lower) side of the sensor housing 100, a row of third ventilation holes 112 on the front side of the sensor housing 100, and a row of fourth ventilation holes 113 on the rear side of the sensor housing 100. The first ventilation holes 111, second ventilation holes 114, third ventilation holes 112, and fourth ventilation holes 113 are all evenly spaced along a straight line, and the first ventilation holes 111 and second ventilation holes 114 are symmetrically arranged, as are the third ventilation holes 112 and fourth ventilation holes 113. This ventilation system allows air to flow into the sensor housing 100, ensuring air circulation and not affecting the detection performance of the CO2 acquisition probe 240 inside the sensor housing 100.

[0030] In a specific embodiment, the axis of the ventilation hole is inclined relative to the side wall of the sensor housing 100, preferably at an angle of 45°. Furthermore, a row of first baffles 161 is provided on the inner surface of the front and rear side walls of the sensor housing 100. The first baffles 161 are perpendicular to their respective side walls and are respectively positioned on one side of the third ventilation hole 112 and the fourth ventilation hole 113. An airflow channel is formed between adjacent first baffles 161. The third ventilation hole 112 and the fourth ventilation hole 113 are located within this airflow channel, and their symmetrical arrangement ensures air circulation. It is understood that the light emitted from the CO2 collection probe 240 cannot escape the sensor housing 100 due to the obstruction of the first baffles 161 and the inclined ventilation holes, thus avoiding any impact of CO2 sensor emission on plant growth.

[0031] Similarly, a row of second baffles 162 is provided on the inner surface of the upper and lower side walls of the sensor housing 100. The second baffles 162 are perpendicular to their respective side walls and are respectively located on one side of the first ventilation hole 111 and the second ventilation hole 114. An airflow channel is also formed between two adjacent second baffles 162. The first ventilation hole 111 and the second ventilation hole 114 are located in the aforementioned airflow channel, and the symmetrical arrangement of the first ventilation hole 111 and the second ventilation hole 114 ensures airflow. It can be understood that the light emitted from the CO2 acquisition probe 240 cannot escape from the outside of the sensor housing 100 due to the obstruction of the second baffles 162 and the inclined ventilation holes, thereby avoiding the impact of CO2 sensor light emission on plant growth.

[0032] In some embodiments, the head of the sensor housing 100 is provided with a hook 120 to facilitate hanging the CO2 sensor indoors.

[0033] In some embodiments, the sensor housing 100 has a wire hole 130 at its tail end, a display window 140 and a backlight button hole 150 on its front side, and a detection tube 180 inside the sensor housing 100. One end of the detection tube 180 is connected to the ventilation hole for mounting internal components (display 210, backlight button 220 and temperature and humidity detection probe 260) and connecting wires 230.

[0034] In some embodiments, the sensor housing 100 includes a detachably connected upper shell 101 and a lower shell 102. Specifically, the upper shell 101 is provided with a connecting post 170 and the connecting post 170 is provided with a threaded hole, and the lower shell 102 is provided with a mounting hole 190. A screw is threaded through the mounting hole 190 and threaded into the threaded hole on the connecting post 170 to realize the assembly of the upper shell 101 and the lower shell 102.

[0035] Reference Figure 7-8 An embodiment of this utility model also provides a CO2 sensor, including a sensor housing 100 and a PCB motherboard 250, a CO2 acquisition probe 240, a display screen 210, and a backlight button 220 disposed inside the sensor housing 100. The CO2 acquisition probe 240, the display screen 210, and the backlight button 220 are integrated on the PCB motherboard 250. The display screen 210 is located at the display window 140 provided on the sensor housing 100. The backlight button 220 is located in the backlight button hole 150 provided on the sensor housing 100. The PCB motherboard 250 is connected to a connecting wire 230, which passes through a wire hole 130 provided at the tail of the sensor housing 100.

[0036] Furthermore, the PCB motherboard 250 also integrates a temperature and humidity detection probe 260, which is located in the detection tube 180 disposed inside the sensor housing 100.

[0037] It is understood that in this embodiment, the CO2 acquisition probe 240 is used to detect the concentration of CO2 in the air, and the temperature and humidity detection probe 260 is used to detect the temperature and humidity of the environment. The temperature and humidity detection probe 260 is isolated from the inside of the sensor housing 100 through the detection tube 180 and is connected to the external environment through the ventilation hole, thereby improving the accuracy of the detection. The display screen 210 is used to display the data of CO2 concentration and ambient temperature and humidity. The backlight button 220 is used to turn off the backlight of the display screen 210, keeping the display screen 210 in a screen-off state to avoid affecting plant growth. The display screen 210 is turned on by using the backlight button 220 when data needs to be viewed.
