Low-power UHF-RFID sensor tags for a complete monitoring and traceability of the cold chain

This paper focuses on the development of an intelligent monitoring system for logistic management. The system is a profitable combination of Radio-Frequency-Identification (RFID) Technology and variable sensor types, like temperature, humidity or gas sensors. Depending on the requirements, the integration of different sensors is possible. In this case the main attention is turned on the temperature monitoring in truck environment during the food transport. Of course, the setting is transferable on other applications like monitoring temperature of pharmaceuticals or controlling of humidity to prevent corrosion of car components during transport. Furthermore, the system is capable to communicate with the driver's cabin and with a central base in case of temperature range violation, allowing the driver or the fleet manager to proactively intervene before damage occurs.
