Abstract
A device for detecting the state of a leaf of doors, gates or the like, including a magnetometer that can move with respect to a reference geometric plane that has a substantially fixed orientation with respect to an external magnetic field, the magnetometer being connected to a control unit that is configured to produce a movement of the magnetometer with respect to a preset position, on the basis of a measurement of the external magnetic field which is detected by the magnetometer; in addition or as an alternative to the magnetometer, the device can include an accelerometer.
Claims11
A device for detecting the state of a leaf of doors or gates comprising a knob rotatable about its own axis perpendicularly to a plane and a magnetometer fixed on said knob, said magnetometer being movable with respect to a reference geometric plane and being rotatable with respect to said axis of rotation of said knob, said geometric plane having a substantially fixed orientation with respect to an external magnetic field, said magnetometer being connected to a control unit of the device, said control unit being configured to determine a movement of the magnetometer with respect to a preset position, on the basis of a measurement of said external magnetic field detected by said magnetometer, the device further comprising an accelerometer fixed on said knob, the accelerometer connected to said control unit for detecting the rotation of said knob in the plane and also to determine the angle of rotation of the magnetometer with respect to said axis of said knob.
