Temperature Reader sending out RF signal to sensors, RF signal energized and wakes up sensor to perform temperature sensing, after measure the temperature, the sensors return the measured temperature to reader. The whole process is carry out under digital communication manner, with CRC error correction mechanism. 

Integrated RFID Sensor Chip 

A tiny microchip integrates RFID and temperature sensor, each sensor has an unique ID, no need for external sensor. Ultralow power consumption secures the reading distance. Perfect for the switchgear temperature application.
