Problems solved by technology
The wired connection method of 485 interface increases the workload of installation, and the complicated connection brings great inconvenience to the maintenance of temperature and humidity sensors.
[0009] (2) Using an external power supply for power supply will inevitably increase the power cord
In addition, the length of the power line limits the layout range of the sensor
[0010] (3) In greenhouse planting, for some important parameters, it is not only the detection of temperature and humidity, but the existing technology can only detect temperature and humidity, and the function is relatively simple

The invention discloses a low-power wireless temperature and humidity sensor. The sensor adopts a low-power wireless design, so as to prevent the installation and maintenance cost and limitation caused by complex wiring. The sensor comprises a power supply; a controller used for transceiving and analyzing control instructions and carrying out parameter calculation; a temperature and humidity sensor used for detecting temperature and humidity in air having a signal output end being in communication connection with a signal end of the controller; a silicon photocell used for detecting the numerical value of illuminance in the environment and having a signal output end being in communication connection with a signal end of the controller; and a wireless module used for wirelessly communicating the controller with a terminal and having a signal end being in communication connection with a signal end of the controller. Wired 485 interface communication is changed into LORA wireless communication, and external wired power supply is changed into battery power supply. In addition, a module for detecting illuminance is additionally arranged. Compared with the prior art, the invention has the following beneficial effects: data lines and power lines are reduced, the maintainability of the product is enhanced, and the flexibility is high.
Description
technical field [0001] The invention relates to sensor technology, in particular to a low power consumption wireless temperature and humidity sensor. Background technique [0002] Temperature, humidity and light are particularly important in modern agricultural planting. For example, in the cultivation of greenhouse crops, temperature and humidity directly determine the yield and quality of the crops. It is an important indicator to measure the output of greenhouses. In order to have a higher yield of crops and realize the concept of cross-season, it is necessary to strengthen the regulation of temperature and humidity. [0003] In most greenhouses, the adjustment of greenhouse temperature is related to the yield of crops. The current technology mainly uses: [0004] (1) The way of wired connection adopts 485 interface and MODBUS protocol to realize wired connection. [0005] (2) The power supply adopts high power consumption 10~30V DC point voltage wired power supply. ...
