Abstract
A sensor device includes: a first sensor group () in which a plurality of first vibration sensors for detecting vibration acceleration in one direction with respect to an object to be detected are arranged to face the same direction; a phase difference calculation unit () which, based on a plurality of first signals indicating the vibration acceleration detected by each of the plurality of first vibration sensors included in the first sensor group (), calculates a first phase difference indicating the phase difference between the plurality of first signals; and an acceleration calculation unit () which, using the first phase difference and the plurality of first signals, calculates vibration acceleration in a first direction perpendicular to a surface on which the plurality of first vibration sensors are arranged, and vibration acceleration in a second direction parallel to the surface on which the plurality of first vibration sensors are arranged.
