The temperature detection threshold is adjustable via a potentiometer. It uses the LM393 based voltage comparator chip which features a clean and stable digital output signal and a driving ability of 15mA.

The DO output can be directly connected to the microcontroller, and it outputs a high or low-level voltage depending on the temperature changes from the environment.

The DO output can be used directly drive a relay module or as a thermostat switch for controlling external equipment, such as a cooling fan.
