Ceramic Humidity Sensitive Resistor

What's Ceramic Humidity Sensitive Resistor ?

Ceramic Humidity Sensitive Resistor is a humidity sensitive resistor device for sensing the humidity of an ambient atmosphere. The device has a humidity sensitive resistor formed by a metal oxide sintered substrate having electrodes on one surface thereof, the resistivity of the humidity sensitive resistor decreasing as the ambient humidity which can affect the surface of the humidity sensitive resistor increases; and a heater positioned near the Humidity Sensitive Ceramic Resistor for applying radiant heat to the surface of the humidity sensitive resis-tor, which heater can be used for improving the sensitivity of the humidity sensitive resistor. By the application of a slight amount of radiant heat, the humidity sensitivity increases, and by the application of a large amount of strong heat, stains which may be on the surface of the humidity sensitive resistor.
