Abstract
In a tracking device, a crescent-shaped printed circuit board partially encircles a battery to minimize a thickness of the tracking device. A speaker and a light-emitting diode emit alerts upon receiving a command of a control apparatus or in response to a motion or a temperature sensed by a sensor. A local network has one hub for tracking a plurality of tracking devices and a wider area network has multiple hubs for more detailed tracking of the plurality of tracking devices. The wide area network tracks the plurality of tracking devices anywhere and stores data of each tracking device including its last known position and its sensor data.
