ABSTRACT:
An acceleration sensor comprises a mass, which can be deflected in a first direction and a second direction opposite to the first direction, a driver effective to vibrate the mass, a detector for detecting times when the mass passes a predetermined position when an acceleration is applied, and an evaluator which detects the acceleration based on the detected times during acceleration and times when the mass passes the predetermined position when no acceleration is applied. Thereby, it is achieved that the acceleration is detected inexpensively and accurately.
