Abstract

PURPOSE: To detect the state changes of temperature, humidity, etc. by having a sensor means indicating constant changes in correspondence to the state changes of temperature and humidity.
CONSTITUTION: A power source 6 applies a voltage to a sensor means 4 and reference resinstance 8 via switch means 7. The voltage to be applied can be either AC or DC. An electric control circuit 9 operates according to the contents operated by the user from a operating part 11. The electronic control circuit 9 supplies a power source to the sensor means 4 by energizing the switch means 7 and is inputted with the signal voltage VSG determined by the ratio of the resistance value between the reference resistance 8 and sensor means 4. When the signal voltage VSG is unnecessary, the power supply to the sensor means 4 may be turned OFF by de- energizing the switch means 7.
