Devices designed to detect the amount of heat using different techniques and in different mediums.
Thermistors NTC (Negative Temperature Coefficient)
Devices that change their resistance in reaction to changes in temperature. In a NTC (Negative Temperature Coefficient) thermistor, the resistance decreases as the temperature increases.
Thermistors PTC (Positive Temperature Coefficient)
Devices that change their resistance in reaction to changes in temperature. In a PTC (Positive Temperature Coefficient) thermistor, the resistance increases as the temperature increases.
