In the framework of the “GoodFood” FP6 Integrated Project [1], a flexible transponder gas sensing system with RFID communication capabilities for food logistic applications is being proposed. The transponder, besides storing dynamic traceability information, features physical sensors (relative humidity (rH), temperature, light) and, depending on the application scenario, will also feature chemical gas sensors. In this work, low-power front-end electronics based on a Texas Instruments MSP430 [2] microcontroller ...
