What is Thermistor? How Thermistors Work? Temperature Measurement

Thermistor is a type of temperature sensor. Thermistors are semiconductor devices that are used to measure temperature. The name comes from a combination of the words "resistor" and "thermal". Thermistors have an electrical resistance that is proportional to temperature. From a general physics course on electricity and magnetism, you may have learned that this is a property typical for all conductors. For example, devices such toasters, heaters, and light bulbs operate on this principle. Thermistors are different in that they are created to deliberately exploit this effect, and hence are more temperature sensitive than usual.
