Device (1) for detecting the state of a leaf (10) of doors, gates or the like, comprising a magnetometer (2) that can move with respect to a reference geometric plane (x′-y′) that has a substantially fixed orientation with respect to an external magnetic field (B→), the magnetometer (2) being connected to a control unit (3) that is configured to produce a movement of the magnetometer (2) with respect to a preset position, on the basis of a measurement of the external magnetic field (B→) which is detected by the magnetometer (2); in addition or as an alternative to the magnetometer (2), the device (1) can comprise an accelerometer (5). |
