摘要: According to one embodiment, a sensor includes a sensor element, a housing provided around the sensor element, and a processor. The sensor element includes a base body including first and second base body regions, and first and second sensor parts. The first sensor part is provided in the first base body region, and includes a first sensor movable part. The second sensor part is provided in the second base body region and includes first and second beams. The processor can derive a rotation angle and an angular velocity based on a signal obtained from the first sensor movable part. The processor can detect acceleration and a temperature based on a first resonance frequency of the first beam and a second resonance frequency of the second beam. The processor can correct one of the rotation angle or the angular velocity based on one of the temperature or the acceleration.
