The greenhouse temperature controller transmits the temperature in the greenhouse to the microcomputer processor through the temperature sensor. When the temperature is inappropriate, the microcomputer processor will send out a high or low working signal to drive the motor to drive the reducer to work. The reducer is connected with the iron pipe, and the iron pipe pulls the tuyere rope to adjust the temperature.

The temperature controller adopts digital control technology, and the NTC temperature sensor inside the temperature controller detects the indoor temperature, and compares it with the temperature set by the user in real time, and automatically adjusts the opening and closing of the tuyere, so as to finally achieve the purpose of maintaining the indoor constant temperature.
