ABSTRACT:
An acceleration sensor includes a sensing unit for detecting impact acceleration and a signal processing unit for measuring the magnitude of the detected acceleration. The signal processing unit has functions of calculating the sensitivity of the sensing unit when specific acceleration is applied to the sensing unit in an inspection stage, storing the calculated sensitivity, and correcting the output of the sensing unit according to the stored sensitivity in actual operation.
