Product Introduction
The thermistor module is highly sensitive to environmental temperature and is typically used to detect the temperature of the surrounding environment. It employs an NTC thermistor sensor with excellent sensitivity. The temperature detection range is from 20°C to 80°C. The sensor is specially equipped with M3 fixing installation holes, allowing for easy adjustment and fixed installation. A wide-voltage LM393 comparator is used, resulting in clean signals, good waveforms, strong driving capability, exceeding 15mA, with a variable precision potentiometer for adjusting the sensitivity.

Usage Instructions
- The thermistor module is highly sensitive to environmental temperature and is generally used to detect the temperature of the surrounding environment.
- By adjusting the potentiometer, the threshold for temperature detection (the control temperature value) can be changed. For example, if the desired environmental temperature is 50℃, the module will turn on its green light when the corresponding environmental temperature is adjusted to this value, and the DO will output a low level. When the temperature is lower than this set value, it will output a high level, and the green light will not be on.
- The DO output terminal can be directly connected to the digital 3 pin of Arduino uno. Through Arduino uno to detect the high and low levels, this can be used to detect changes in the environment’s temperature.
- The DO output terminal can also directly drive the relay module, thus forming a temperature control switch to control the working temperature of related equipment. It can also be connected to a fan for cooling, etc.
- The temperature detection range of this module is 20-80 ℃.
- This module can also be replaced with a wired temperature sensor for controlling water temperature, water tanks, etc.
- The analog output AO of the small board (4-pin thermistor module) can be connected to the analog input A0 pin of Arduino uno. Through AD conversion, more accurate values of the environmental temperature can be obtained.
Application
- Thermistors can be used as electronic components in instrument circuits for temperature compensation and cold junction temperature compensation of thermocouples. The self-heating characteristic of NTC thermistors can be utilized for automatic gain control, forming RC oscillators for amplitude stabilization circuits, delay circuits and protection circuits. When the self-heating temperature is much higher than the ambient temperature, the resistance is also related to the heat dissipation conditions of the environment. Therefore, in flow meters, flow gauges, gas analyzers, thermal conductivity analyzers, the characteristic of thermistors is often utilized to make dedicated detection elements. PTC thermistors are mainly used for overheat protection of electrical appliances, contactless relays, temperature control, automatic gain control, motor starting, time delay, automatic demagnetization of color TV, fire alarm and temperature compensation, etc.
- Thermistor sensors are widely used in household appliances, automotive electronics, industrial control and medical equipment. For example, in household appliances, thermistors can be used to control the start and stop of fans to maintain the normal working temperature of the equipment. In smartphones, NTC thermistors are used to monitor the internal temperature to prevent overheating.
