NTC Thermistor Sensor

NTC Thermistor Sensor

This thermistor module features a digital output NTC temperature sensor that allows you to easily add the capability of detecting high and low-temperature conditions to your new project.

The temperature detection threshold can be adjusted with a potentiometer.

It uses an LM393-based voltage comparator chip that provides a clean and stable digital output signal and has a 15 mA driving capability.

The DO output can be directly connected to a microcontroller and provides a high or low-level voltage depending on changes in ambient temperature.

The DO output can be used as a thermostat switch to control external equipment such as a relay module or a cooling fan.

It can be used with many microcontrollers, including Arduino.
