Temperature Tag Based on Active RFID


Article Preview

In view of the problems that we can not real-time monitor and record temperature even when the temperature exceeds a certain limit the system can not alarm, leading to deterioration of food rotting in the refrigerated transport process. So we propose and establish a real-time monitoring and recording system based on active RFID technology. The system uses active RFID technology characteristics and the communication protocol between the Reader and the host computer to monitor and record the temperature during transport. The configuration of the tag can widen the range of applications, so you can change the parameters of the tag with configurator. The tag's size is small and it has flexible applicability and strong adaptability. Test results show that the general range of temperature tag is -50~120°C between the error of ± 1°C. The rate of Reader is 100%, and the tag can launch to about 100 meters. The system does not only solve the problem of temperature during refrigerated transport, but also provides a theoretical for long-distance transmission of RFID.
