NTC Thermistor Sensor Board
This thermistor module features an NTC temperature sensor that provides digital output, allowing you to easily add over-temperature and under-temperature detection capabilities to your new project.
The temperature detection threshold can be adjusted by potentiometer.
Uses the LM393-based voltage comparator chip, which offers a clean and stable digital output signal and 15 mA driving capability.
DO output can be connected directly to the microcontroller and outputs a high or low level voltage depending on temperature changes in the environment.
DO output directly It can be used as a thermostat switch to control a relay module or external equipment such as a cooling fan.
It can be used with many microcontrollers, especially Arduino.
