Abstract

PURPOSE: To enable direct control of a device and simplify the whole of the device by a method wherein a humidity-sensitive element is built in an AC voltage generating part and thereby it is made to rely on the humidity.
CONSTITUTION: A device is provided with an AC voltage generating part A, a DC voltage converting part B and an output part C. When the humidity is low, the resistance value of a humidity-sensitive element 6 is high, the amplification degree of an operating amplifier 7 turns low, the oscillation is stopped and AC voltage is not outputted from the part A. Accordingly, the output of the parts B and C becomes zero. When the humidity exceeds a fixed value, the amplification degree of the amplifier 7 turns to be large, the part A operates, the AC voltage of fixed frequency is outputted and impressed on another operating amplifier 12 and the load is made to act, thereby dehumidifying operation is performed and the humidity in a room is maintained at the level lower than the reference humidity.
