Abstract
A sensor system includes a sensor circuit and a plurality (e.g., N-number) of radio frequency identification (RFID) tags. The sensor circuit senses a physical parameter and supplies N-bits of digital sensor data. Each of the RFID tags at least selectively receives a digital sensor signal representative of one of the N-bits of digital sensor data and selectively transmits the digital sensor signal it received.
