What is a thermistor? | Omega Engineering

A thermistor sensor is a temperature-sensing element composed of sintered semiconductor material which exhibits a large change in resistance proportional to a small change in temperature. Thermistors usually have negative temperature coefficients which means the resistance of the thermistor decreases as the temperature increases.

Thermistor Basics, Working Principle, Types and Applications

23/07/2019· Temperature Controlled Load by Thermistor Sensor. The main aim of this project is to design a circuit to control a load automatically using a thermistor sensor with a fixed temperature limit. When the temperature increases beyond an exact limit, a lamp is switched ON to bring the temperature to a normal value. Due to the automatic switch On of the load, this system doesn’t require human ...
