This NTC thermistor module has an NTC temperature sensor which gives an only digital output that allows you to easily add over-temperature and under-temperature condition sensing capabilities to your new project. 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.

Step 1: Introduction


Thermistor Sensor Module is used to sense temperature and convert it into output signals. It is associated with both analog output pin and digital output pin labelled as AO and DO respectively on the board. Thermistor Sensor Module is made of semiconductor materials. Basically thermistor sensors are mostly Negative Temperature Coefficient (NTC), which means NTC thermistors will have their electrical resistance decreased when subjected to an increase in body temperature. This module has a potentiometer knob that can be adjusted to change the sensitivity of thermistor towards temperature.
