Tinynose, an Auxiliary Smart Gas Sensor for RFID Tag in Vegetables Ripening Monitoring During Refrigerated Cargo Transport

摘要

Current state of the art's real time monitoring of fresh produce, provides only temperature and humidity information. The idea is to develop new sensors and transport service assisted by ICT platform to monitor fresh produce quality. The technology will be based on radio frequency (RF) wireless network, and will provide real-time and in-site data-logging, enabling active management of food products in storage and transit. The RF sensor network design, allows an auxiliary sensor node to be "plugged in". In this contribution we present the commercial platform developed starting from o fork of open hardware on which we assemble an array of commercial sensors in an "open air" configuration. We developed for this Embedded Gas Sensor System Device (Tinynose) two set-up: the "Development set-up" that uses a star wireless network infrastructure to store all raw sensor output and associated measurement error in a server DB to define parameters in ripening mathematical model and the "TAG set-up" that performs ripening evaluation in ICT in-site platform.
