Generic NTC Thermistor Temperature Sensor Module - Digital Switch Output, 3.3V-5V
This NTC thermistor temperature sensor module provides a digital switch output for easy integration with microcontrollers like Arduino, Raspberry Pi, and ESP32. Operating from 3.3V to 5V, it features an adjustable threshold via potentiometer for temperature control applications within a -25°C to +80°C range.
Features
- Digital comparator output (high/low) for direct microcontroller interface.
- Adjustable temperature detection threshold via onboard potentiometer.
- Wide operating voltage range from 3.3V to 5V DC.
- Compact PCB with mounting hole for secure installation.
- Utilizes a sensitive NTC thermistor for ambient temperature sensing.

This module employs an NTC (Negative Temperature Coefficient) thermistor, whose resistance decreases predictably with rising temperature. The signal is conditioned by an LM393 voltage comparator, which provides a clean digital output switch at a user-defined threshold set by the potentiometer. This design offers a simple, robust method for temperature monitoring without requiring analog-to-digital conversion on the host controller.
The module is designed for durability in typical electronic environments, featuring a standard PCB construction suitable for prototyping and embedded systems. Its digital output can directly drive small loads or interface with relays, making it ideal for creating temperature-activated switches in automation projects.
