1. A computer-implemented method, comprising:
- maintaining a compass in a sleep mode to conserve energy;
changing the sleep mode to an awake mode for the compass upon an occurrence of one or more conditions selected from the group consisting of;
a detection of a movement of an object by an accelerometer;
a detection of a change in a position of the object by a magnetic sensor; and
a time of awakening based on a predetermined schedule,wherein the compass consumes more energy in the awake mode than in the sleep mode;
when the compass is in the awake mode, receiving an orientation signal from the compass; and
determining a change in the orientation of the object based at least upon the orientation signal from the compass.

Abstract
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.

13. A computer-implemented method, comprising:
-
maintaining a compass in a sleep mode to conserve energy; changing the sleep mode to an awake mode for the compass upon an occurrence of one or more conditions selected from the group consisting of; a detection of a movement of an object by an accelerometer; a detection of a change in a position of the object by a magnetic sensor; and a time of awakening based on a predetermined schedule, wherein the compass consumes more energy in the awake mode than in the sleep mode; receiving input from an accelerometer; when the compass is in the awake mode, receiving input from the compass; 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. - View Dependent Claims (14, 15, 16, 17)

18. A system, comprising:
-
a non-transitory computer-readable storage medium, configured to store data generated by a sensor package comprising at least one of an accelerometer and a compass, the sensor package associated with an object having an orientation; a processor communicatively coupled to the non-transitory computer-readable storage medium, the processor configured to; maintain the compass in a sleep mode to conserve energy; change the sleep mode to an awake mode for the compass upon an occurrence of one or more conditions selected from the group consisting of; a detection of a movement of an object by an accelerometer; a detection of a change in a position of the object by a magnetic sensor; and a time of awakening based on a predetermined schedule, wherein the compass consumes more energy in the awake mode than in the sleep mode; when the compass is in the awake mode, receive an orientation signal from the compass; determine a change in the orientation of the object based at least upon the orientation signal from the compass. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
