ABSTRACT:
A vibration detecting sensor includes a pair of piezo-electric elements electrically connected together using a plate member, which eliminates the influences of temperature change to the surroundings by using a temperature compensating piezo-electric element, and prevents external noises from entering the device. Therefore, vibrations are detected efficiently.
