Abstract
A sensor module may be mounted in an electronic device including a rotating body rotatably arranged inside a housing. The sensor module may include a stator fixed in the housing; an energy harvester including a rotor mounted in the rotating body, at a position to at least partially face the stator; and a sensor arranged inside the rotating body together with the rotor, wherein, as the rotating body rotates, the rotor may be configured to rotate about the stator and generate an induced current and supply same to the sensor. The sensor may be configured to detect, using power based on the induced current, environmental information of the inside of the rotating body or operating state information of the rotating body.
