RFID UHF Temperature Sensor Tags Initialization and Application

Radio Frequency Identification (RFID) has found its appliance in many areas but most common use of RFID technology is for tracking various goods. In this paper the system for monitoring temperature of instruments inside the laboratory is presented. System is composed of Caen RT0005 UHF RFID tags with integrated temperature sensor, Alien 9900 UHF RFID reader and UHF RFID Alien patch antennas. Caen RT0005 tags are semi-passive tags which provide temperature logging once when they are initialized. Proposed system represents safe surveillance of expensive instruments prone to overheating. We proposed the software which provides instruments tracking inside the laboratory, initialization and writing of sensor tags, temperature tracking and alarms notification. There are two kinds of temperature alarms which can be alerted: i) when temperature increases over pre-set temperature limit, ii) when temperature is increased rapidly inside pre-set time interval. Experimental results of proposed application are induced at the end of the paper along with the advantages and disadvantages of the proposed system.
