Abstract:
A sensor package is disclosed that includes, a compass, an accelerometer, and an electromagnetic flux tag based open/close sensor. The compass may be activated by a microcontroller in response to an indication of movement detected by an accelerometer. The compass's data may be utilized to determine an orientation for the object such as a door on which the sensor package is situated. The orientation data may indicate that the door is ajar and/or that a second magnetic field is present, suggesting tampering. A notice may be dispatched to a controller for the home security system, a client device, a remote system, etc.
