Abstract

The inclination sensor includes a gimbal mechanism rotatably supported around a first shaft and a second shaft, a first motor, a second motor, an acceleration sensor disposed in the gimbal mechanism with an origin point of coordinate axes being coincident with a point of intersection of a shaft center of the first shaft and a shaft center of the second shaft, and a control unit that simultaneously rotates the first shaft and the second shaft to continuously rotate the acceleration sensor around the first shaft and the second shaft and applies frequency analysis to the output values from the acceleration sensor to arithmetically determine the inclination angle with respect to the horizontal direction.
