摘要： A sensor device capable of accurately sensor humidity using a pair of sensing elements in which the sensor device contains a pair of sensor elements and are negligibly variable against variations in the physical volume of humidity in comparison to variations in the temperature of these sensor elements. The sensor device is comprised of a pair of sensor elements connected in series, in which one of these generates an output corresponding to the physical volume of humidity while sensing is still underway, whereas the other preserves the output so that it cannot be affected by variations in the physical volume, of humidity while sensor characteristics employed to sense the physical volume of humidity are variable depending on temperature; a current control circuit capable of supplying a large amount of current to a serial circuit comprised of a pair of heaters when the temperature of the sensor elements decreases and conversely supplying a small amount of current to the same circuit when the temperature of the heaters rises; and a sensor detecting any variation in signal output from one of the sensor elements.
