A thermistor is a resistance thermometer, or a resistor whose resistance is dependent on temperature. ... When temperature increases, the resistance increases, and when temperature decreases, resistance decreases. This type of thermistor is generally used as a fuse.

How does a thermistor measure temperature?

Thermistors are available in two types: those with Negative Temperature Coefficients (NTC thermistors) and those with Positive Temperature Coefficients (PTC thermistors). NTC thermistors' resistance decreases as their temperature increases, while PTC thermistors' resistance increases as their temperature increases.

What is a thermistor used for and how does it work?

Thermistors change resistance with temperature changes; they are temperature-dependent resistors. They're perfectly suited to scenarios where one specific temperature needs to be maintained, they're sensitive to small changes in temperature. They can measure liquid, gas, or solids, depending on the type of thermistor.
