3-Pin Thermal Thermistor Temperature Sensor Module

Description:

The 3-Pin Thermal Thermistor Temperature Sensor Module provides an accurate and reliable solution for ambient temperature detection in your electronics projects. This module utilizes an NTC (Negative Temperature Coefficient) thermistor, a highly sensitive resistor whose resistance decreases significantly as its surrounding temperature increases. This resistance change is then converted into a measurable analog voltage output, making it easy to interface with microcontrollers.

Beyond its core temperature sensing capability, this module often includes an onboard comparator (like the LM393) and a potentiometer (trimmer). This allows for both an analog output (proportional to temperature) and a digital output that acts as a temperature switch. You can easily adjust the digital output's trigger threshold using the potentiometer, enabling the module to activate an alarm, turn on a fan, or trigger other actions when a specific temperature is reached.

Compact and versatile, this module is perfect for a wide range of applications, from smart home systems and environmental monitoring to educational experiments and DIY thermostats. Its clear pinout and integrated components simplify wiring and make it a highly practical choice for hobbyists and makers using Arduino, ESP32, Raspberry Pi, and similar development boards.
