Flexible tag datalogger for food logistics

This paper describes the design, development, and testing of a Flexible Tag Datalogger (FTD) for improving food and goods logistics during transport, storage and vending. This miniaturized device integrates three sensors (temperature, humidity and light) and a microcontroller, which manages the sensors in a power safe mode and records the ranges of the measures on its memory. The transmission of data is based on an infrared communication (as alternative to the RFID technology), making the device able to communicate with the most common personal devices, such as Smartphone or PDA with integrated infrared port.
