Abstract: An exemplary method relates to determining an open/closed position of a door. The method generally involves generating, by a multi-axis magnetometer mounted to the door, a plurality of signals relating a magnetic field having a net magnetic flux point, and generating, by a controller and based on the plurality of signals, a current incidence angle defined between the multi-axis magnetometer and the net magnetic flux point. The method further includes comparing the current incidence angle to a known incidence angle, wherein the known incidence angle is defined between the multi-axis magnetometer and the net magnetic flux point when the door is in a known position. The method further includes determining the open/closed position of the door based on the comparison of the current incidence angle to the known incidence angle.
