What are thermistors?

Thermistors, derived from the term thermally sensitive resistors, are a very accurate and cost effective method for measuring temperature. Thermistors are usually two-terminal semiconductor devices made from semi-conductor materials that have an electrical resistance that varies non-linearly with temperature (see Figure 1). Some materials provide better stability while others have higher resistance ranges and are fabricated into smaller thermistors.  Each specific thermistor has its own unique resistance versus temperature characteristic.
