A thermistor is a type of resistor whose resistance is dependent on temperature, more so than other types of resistors. Thermistors are widely used as temperature sensors, and can be incorporated into building management systems (BMS) to help control heating, ventilation, and air conditioning (HVAC) systems. A thermistor is a type of resistor that is used to measure temperature.
Thermistors are made from materials that have a high resistance to electricity at low temperatures and a low resistance at high temperatures. The resistance of a thermistor changes with temperature, so it can be used to measure temperature.
