A sensor apparatus includes: a detection unit which includes a 3-axis acceleration sensor and a temperature sensor; and a processing unit which includes an acceleration vector calculating unit, a total acceleration calculating unit for calculating the magnitude of an acceleration vector, a tilt angle calculating unit for calculating tilt angles from the acceleration vector, and a temperature calculating unit. The tilt angle calculating unit discontinues the processing of calculating the tilt angles if the magnitude of the acceleration vector is different from that of gravitational acceleration.
