4PIN NTC Thermistor Temperature Sensor Module
The NTC Thermistor Temperature Sensor Module is a compact and cost-effective solution for measuring ambient temperature. It is highly sensitive to temperature changes, making it ideal for detecting environmental temperature fluctuations. The module allows for easy adjustment of the temperature threshold using a potentiometer.
The Digital Output (DO) pin can be directly connected to a microcontroller, enabling it to detect high or low temperature levels based on changes in the surrounding environment.
With a temperature detection range between 20°C and 80°C, this module is suitable for various applications, such as water temperature control in tanks or other similar systems.
For more accurate temperature measurements, the four-wire method of thermistor measurement is recommended. This method minimizes the impact of cable resistance, ensuring more precise readings.

4PIN NTC Thermistor Temperature Sensor Module Overview
The 4PIN NTC Thermistor Temperature Sensor Module is a compact board that uses a four-wire NTC thermistor and an LM393 comparator to provide both analog and digital temperature outputs. Designed for easy integration with microcontrollers, it reliably monitors ambient temperatures from -25°C up to +80°C and signals when a preset threshold is crossed.
Key Features of 4PIN NTC Thermistor Temperature Sensor Module
- Wide sensing range: -25°C to +80°C

How to Use 4PIN NTC Thermistor Temperature Sensor Module
Connect VCC to a 3.3–5 V supply and GND to ground. Wire the AO pin to an ADC input on your microcontroller for continuous temperature readings, and wire DO to a digital input to detect when temperature crosses the set threshold. Rotate the onboard potentiometer while monitoring DO until it switches at your desired temperature point.

Frequently Asked Questions
How do I interface the sensor with an Arduino?
Connect VCC to the Arduino 5 V pin and GND to its ground. Attach AO to an analog input (e.g., A0) for voltage-based readings and DO to a digital pin for threshold alerts. In your sketch, read analog values via analogRead() and digital state via digitalRead().
How can I set the temperature threshold for the digital output?
Power the module, then place it in an environment near your target temperature. Slowly turn the onboard potentiometer until the DO pin toggles its state at that temperature. Lock the setting by tightening any holding nut on the pot if provided.
What temperature range does this module support?
The built-in NTC thermistor accurately senses temperatures from -25°C up to +80°C. For environments beyond this range, consider sensors rated for higher or lower extremes.
