<p>A sensor device (10) has a detection section (12) and a processing section (14). The detection section (12) has a three-axis acceleration sensor (20) and a temperature sensor (22). The processing section (14) has an acceleration vector calculation section (30), a total acceleration calculation section (34) for calculating the magnitude of an acceleration vector, an inclination angle calculation section (32) for calculating an inclination angle from the acceleration vector, and a temperature calculation section (36). The inclination angle calculation section (32) interrupts calculation of an inclination angle when the magnitude of an acceleration vector is different from that of gravitational acceleration.</p> |
