Abstract
A temperature measurement method based on a passive RFID tag. The method comprises: acquiring a circuit temperature feature of a tag multiple times, and establishing a tag temperature-feature correspondence; and estimating, by using the tag temperature-feature correspondence and the current circuit temperature feature of the tag, the temperature of an environment where the tag is located, wherein the circuit temperature feature of the tag is the persistence time within which a passive RFID tag can operate normally during a discharging process after the tag is fully charged. By means of the method, a robust and accurate temperature measurement is achieved, and a tag can be directly deployed on an existing commercial RFID device without modifying the hardware of the tag and a reader.
