Pressure monitoring RFID tag takes 0 bar to 30 bar

December 18, 2014 // By Julien Happich
Built in a compact PCB format, the Cyclon-05BA is a passive RFID tag that integrates a MS5803-05BA sensor from Measurement Specialties to monitor pressures up to 6 bar.

It also integrates a temperature sensor with a range from -30ºC to +85ºC and an accuracy of ±1ºC. Another part from Farsens, the Cyclon-30BA integrated a MS5803-30BA to cover ranges up to 30 bar. These RFID pressure monitor tags are compatible with commercial UHF RFID readers (EPC C1G2).
With a 2W ERP setup the battery-less pressure sensor can communicate to over one meter and a half. The tags come in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960 MHz band.

Such tags could be used in Tire Pressure Monitoring Systems to monitor wheel pressure, removing the need for batteries embedeed inside the tire, hence reducing weight and possible inbalances.
