I. Temperature Measurement Principle
The full name of RFID is Radio Frequency Identification, which is an automatic identification technology that uses radio waves for data exchange.
RFID temperature measurement technology is an innovative application combining RFID wireless identification technology with temperature sensing technology. Its core function is to read temperature data from RFID sensors installed at the temperature measurement point via a receiver, thereby achieving the temperature measurement function of the measurement point.
The main process is for the receiver to transmit a specific electromagnetic wave signal through an antenna. When the passive temperature sensor is within the RF field of the RFID receiver, the sensor's internal antenna receives the electromagnetic wave and converts it into the working voltage required by the internal temperature sensor, MCU, and RF chip, and the internal temperature sensor begins temperature acquisition. Then, the sensor packages the temperature data and the sensor identification code (ID number) into a data frame and transmits it to the receiver as an RF signal via the sensor antenna. After the receiver receives the RF signal feedback from the sensor, it demodulates and decodes it into a digital signal, extracting the sensor identification code and temperature data.
