Intelligent RFID transponder with monitoring functions for sensor data
The integrated UHF (ultra high frequency) technology embedded in the transponder acts, in effect, as a direct control system, and allows mobile parts that do not have their own constant energy supply to be monitored comprehensively.
In this passive mode of operation, in which the system on the transponder side functions without an energy source, is a major advantage of UHF-based control systems, the system obtains its energy from the RFID reader device, and powers the RFID transponder via the transmitted radiation – which in Europe lies in the frequency band from 865 to 867 MHz. The transponder can address external sensors and transmit data to the reading device over a range of up to 3m. The device comes in a range of formats optimised for differing application environments.
