ABSTRACT:
The present invention relates generally to a tag monitoring system network used for tracking object movement. The tags utilized in the system incorporate a motion sensor which detects object movement and includes a signal generation circuit adapted to generate a signal when motion is detected. A microcontroller is provided which is in electrical communication with the motion sensor and includes a transmitter activation circuit wherein said microcontroller includes a preprogrammed transmitter sequence which is activated by receipt of a signal from the motion sensor. A radio transmitter is also provided on the tag which is in electrical communication with the microcontroller, and generates radio signals at the direction of the microcontroller.
