Abstract
An sensor device with high detection accuracy. A time-point measurement unit is provided for measuring time-point information and adding the time-point information to an angular velocity sensing signal and an acceleration sensing signal. The angular velocity sensing signal and the acceleration sensing signal are linked by the time-point information. This structure enables output of the angular velocity sensing signal and the acceleration sensing signal linked by the time-point information. Accordingly, the angular velocity sensing signal can be accurately corrected using the acceleration sensing signal. The detection accuracy of the sensor device thus improves.
