radio frequency identification (RFID) technology is a low-cost and efficient non-contact automatic identification technology, which has the advantages of high recognition speed and recognition distance. A distributed multi-point temperature measurement system based on RFID is designed. The system is composed of temperature acquisition module, wireless transceiver module and host computer module. In order to improve the accuracy of temperature measurement of each node, a temperature compensation algorithm is proposed, and the least square fitting method is adopted to overcome the measurement error caused by the inaccuracy of the device. The results show that the system can effectively accomplish the function of multi point temperature measurement and has high accuracy.
