A device attached to an outside surface of a shipping container for tracking the shipping container includes a solar panel, a battery, a GPS receiver module, a cellular data transceiver module, and a microcontroller for controlling the GPS receiver module and the cellular data transceiver module to periodically obtain the location of the shipping container and transmit the location to a tracking database of a central tracking computer. The solar panel, battery, GPS receiver module, cellular data transceiver module and microcontroller are integrated into a one-piece, watertight master control unit. The master control unit may further include a local wireless network master transceiver module. The local wireless network master transceiver module is for communicating with a wireless sensor located within the shipping container through the walls of the shipping container.
