Thermistors

A thermistor is a type of temperature sensor that is a thermally sensitive resistor. Its resistance changes with temperature, making it a valuable tool for temperature measurement and control. Two primary types of thermistors exist, characterized by the way their resistance responds to temperature changes: Positive Temperature Coefficient (PTC) thermistors and Negative Temperature Coefficient (NTC) thermistors.

An NTC thermistor is known for its property where resistance decreases as the temperature increases. Conversely, a PTC thermistor's resistance increases as the temperature rises. When we delve into the specifics of the negative temperature coefficient, the term essentially implies that as the ambient room temperature goes up, the NTC thermistor's resistance will drop. This characteristic makes NTC thermistors especially valuable for measuring temperature in various applications.

PTC thermistors, on the other hand, are quite the opposite. When the temperature rises, the positive temperature coefficient ensures that the resistance of the PTC thermistor also goes up. PTC thermistors are often utilized in protection circuits and situations where there's a need to react to higher temperatures.
