Abstract
In one aspect the invention provides a magnetic door position detection apparatus adapted to attach to a cabinet interior with a door arranged to transition between an open state where the interior of the cabinet is accessible, and a closed state. The door includes a magnetic field generating structure configured to magnetically engage the door with the cabinet in the closed state. The apparatus provided includes a housing configured to attach to the interior of the cabinet and one or more sensors configured to determine change in the magnetic flux field within the interior of the cabinet induced by motion of the magnetic field generating structure in at least one of three orthogonal axes. The sensor or sensors generate an output signal representing the sensed magnetic field change where the one or more axes is indicative of the cabinet door moved between the closed state and the open state.
