NTC Thermistor Module

NTC Thermistor temperature sensor module is low cost, small size module. It is very sensitive to ambient temperature. It is generally used to detect the temperature of the surrounding environment.

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.
