摘要： According to one embodiment, a sensor includes a fixed member, a movable member, a first counter electrode, a second counter electrode, a first resistance element, a second resistance element, and a control device. The control device includes a controller. The controller performs a first correction operation in a state where the movable member does not receive an external force. In the first correction operation, the controller causes the movable member to generate a first vibration. In the first correction operation, the controller derives a first correction value based on a first detection result of a first component and a second detection result of a second component. The first correction value includes at least one of a first resistance correction value, a second resistance correction value, a first voltage correction value, or a second voltage correction value such that the movable member vibrates along the first direction.

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.

摘要： According to one embodiment, a sensor includes a first beam, a first opposing beam, a support portion, a first linking portion, and a first connecting portion. The first beam includes a first portion and a first other portion. A direction from the first portion to the first other portion is along a first direction. A second direction from the first opposing beam to the first beam crosses the first direction. The first opposing beam includes a first opposing portion and a first other opposing portion. The first linking portion is connected to the first other portion and the first other opposing portion. The first connecting portion is connected to the first linking portion. A first connecting portion width along the second direction of the first connecting portion is narrower than a first linking portion width along the second direction of the first linking portion.
