Temp Guard
Transporting temperature-sensitive goods such as fruit and vegetables or pharmaceuticals is fraught with management headaches: in particular, conventional temperature loggers are relatively expensive, provide no data during transport and are complicated to interrogate. This German project uses inexpensive RFID tags with added sensors that can record and store temperature data, and be read wirelessly at each stage in the product's journey. In this protoype system, data from the RFID reader is sent to an IBM WebSphere RFID Premises Server, which makes it available to a web-based front end. A full record of temperature events during a product's journey allows appropriate decisions to be made quickly both in transit and when it reaches its destination.
