ABSTRACT:
An acceleration sensor includes a piezoelectric element for outputting an electric signal corresponding to acceleration applied thereto, a signal processor for processing a signal outputted from the piezoelectric element, an AC signal outputting device for receiving an externally inputted signal and generating an AC signal which is synchronized with the period of the timing signal in response to receipt of the timing signal and for applying the AC signal to the piezoelectric element, and a capacitor connected between the AC signal outputting device and the piezoelectric element for detecting a fault in the acceleration sensor.
