Abstract
A moisture sensor device includes a sensor portion having a capacitance that is varied in accordance with surrounding humidity, a signal processor for processing a detection signal of the sensor portion and outputting the signal corresponding to the humidity, a heating portion for heating the sensor portion, and a controller for controlling heating of the heating portion so that the capacitance of the sensor portion is substantially equal to a value under predetermined humidity at least during a self-diagnosis period.
