Abstract: An apparatus, method and system are provided which permit the monitoring of a dunnage bag used as a cushion in the transportation of cargo items which may be typically found in as shipping container. A gas pressure sensor may be attached directly to the dunnage bag and the pressure can be monitored remotely. The gas pressure sensor can also be enclosed within a sealed and pressurized enclosure whereby the gas sensor reading can serve as indication of pressure of a nearby dunnage bag within which the enclosure is in contact. The dunnage bag pressure readings can be wirelessly monitored from a remote location and the bag pressure may be controlled remotely.
