Abstract
The present invention is a method, an apparatus, and a system for detecting a change in position of a door or a window in an alarm system. The present invention is a singular housing with a magnetometer for monitoring the magnetic field of the earth, and a microprocessor for detecting a change in the position of the singular housing with respect to the magnetic field of the earth. The microprocessor generates an alarm signal upon detecting the change, and causes the alarm signal to be transmitted, by wireless transmission, to a remote receiving station.
