3 Pin NTC Thermistor Temperature Sensor Module
The NTC Thermistor Temperature Sensor Module is a compact, cost-effective solution for measuring ambient temperature. It is highly sensitive to temperature changes in its environment, making it ideal for monitoring temperature fluctuations. The module features a potentiometer that allows you to adjust the temperature detection threshold.
The Digital Output (DO) can be directly connected to a microcontroller to detect high or low temperature levels based on environmental changes. The temperature detection range for this module is from 20°C to 80°C, making it suitable for various applications such as monitoring water temperature or controlling systems like water tanks.
For the most accurate temperature measurements, the thermistor is typically used with the four-wire method. This approach minimizes resistance introduced by the cables, ensuring precise readings without the interference of additional wire resistance.

Module instructions:
- A thermistor module is sensitive to the environment temperature, are commonly used to detect the temperature of the surrounding environment.
- Through to the potentiometer adjustment, can change the temperature detection threshold (i.e., temperature control), such as the need to control the environment temperature is 50 degrees, while the module corresponding environmental temperature to the green light, the DO output high level, below the set temperature, the output high level, green light don’t.
- The DO output can be attached directly to the single-chip microcomputer, through a single-chip microcomputer to detect the high and low level, thus to detect the temperature of the environment change.
- The DO output can be directly driven by our relay module, which can form a temperature control switch and control related equipment operating temperature, also can connect the fan used for cooling, etc.
- The module of the temperature detection range of 20-80 degrees Celsius.
- This module can also be replaced with a line of a temperature sensor, used for water temperature, control of the water tank, etc.

Frequently Asked Questions
Can I connect this module directly to an Arduino?
Yes. Power the module with 3.3 V–5 V from the Arduino, connect GND, and wire DO to a digital input pin. Use digitalRead() to detect the high/low output when the set temperature threshold is crossed.
What temperature range can this sensor detect?
This module reliably detects temperatures between 20 °C and 80 °C. You can adjust the exact trigger point within that range using the onboard potentiometer.
How much load can the digital output drive?
The comparator output can source or sink over 15 mA, allowing you to drive LEDs, relays via a transistor, or interface directly with logic-level inputs.
