Sensor

Abstract

According to one embodiment, a sensor includes a base, a first detection portion, and a controller. The first detection portion includes a first base electrode fixed to the base, a first fixed portion fixed to the base, and a first element supported by the first fixed portion. The first element includes first and second conductive members. A gap is provided between the first base electrode and the first element. The controller performs first and second operations. In the first operation, the controller is configured to detect a first capacitance signal corresponding to a first capacitance between the first base electrode and a one conductive member of the first conductive member and the second conductive member. In the second operation, the controller is configured to detect a first electrical resistance of an other conductive member of the first conductive member and the second conductive member.
