Radio Frequency Identification Sensors

Abstract

Radio Frequency Identification (RFID) Systems are used when non-line-of-sight operation is required to identify an object and store its information. Some of the applications of this system are toll collection and inventory control. The following paper presents the ongoing research for the Auburn University Detection and Food Safety (AUDFS) project to use RFID technology combined with sensors for detection of pathogens in food. AUDFS aims to integrate the breakthroughs in the detection of food borne illnesses with advances in wireless and biosensor technologies. It explains the basic building blocks and operation of an RFID system. It also illustrates the data transfer process taking place in the system.
