Are There Any RFID Pressure Sensors?
RFID device that can communicate wirelessly (see Michelin Uses RFID to Track Tire Pressure and Tread for London Bus Company and Crane Aerospace and Electronics' RFID-Based Tire Pressure Sensor Simplifies Aircraft Maintenance). There are also active RFID pressure sensors for measuring air pressure within a closed area. RF Code, for example, offers the R160 Air Pressure Sensor, designed specifically for use in data centers. The sensor tags gather environmental data and transmit it via radio frequency communication to fixed and mobile readers every 10 seconds. - See more at: http://www.rfidjournal.com/blogs/experts/entry?10898#sthash.ODhpEKfH.dpuf
