Entry point opening sensor
A sensor package is disclosed that includes a compass and/or an accelerometer. 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.

wherein the accelerometer and the compass are associated with a given object;
comparing the accelerometer input and the compass input to a motion profile for the given object;
based on the comparison, determining that at least one of the accelerometer input and the compass input are inconsistent with the motion profile; and
generating a notice in response to the determined inconsistency.
14. The method of claim 13 , wherein the given object is a door attached to a wall with at least one hinge mechanism, wherein the inconsistency comprises accelerometer input that indicates a displacement greater than a maximum displacement of the door about the at least one hinge mechanism.
