In September 2006 a new transfer project was initiated at the University of Bremen. Scientists of the Microsystems Center Bremen work in close cooperation with several transport companies to capture spatial temperature profiles. The project is founded by the LogdyamicsLab research Cluster.

In this project, 20 or more credit card sized data loggers are placed inside the transport unit. The TurboTag data loggers could store up to 700 measurement points. The measurements are read out via an RFID-Interface. The installation requires minimal effort since the sensors require no wiring.

Short circuits in the air flow or bad thermal isolations could lead to local temperature deviations and a resultant loss in shelf life. The aim of this project is to estimate the magnitude of these effects by practical measurements. Short temperature peaks caused by opening of transport unit doors have only a negligible effect on shelf life and should not trigger an alarm, but a deviation of only 1 °C that lasts over days could lead to an early decay in foods quality. First results confirm that temperature deviations of several °C are present almost everywhere. For correct quality supervision, multiple measurement points are necessary inside the cargo hold.

The field tests will continue under a new transfer project founded by the Deutsche Forschungsgemeinschaft (DFG)
