What types of temperature sensors are there?
Common temperature sensors include thermistors, thermocouples, and integrated circuit types. Thermistors are devices that restrict the flow of electricity in a way that varies with temperature. Thermocouples use two dissimilar metals welded together that generate a small voltage that depends on temperature. Integrated circuits vary a voltage or current that is supplied to them in a way that varies with temperature. Typically, thermistors and IC’s are the preferred types, since they give accurate results with less expense than thermocouples.
