1. A sensor system, comprising:
- a sensor circuit operable to sense a parameter and supply N-bits of digital sensor data; and
N-number of radio frequency identification (RFID) tags, each RFID tag coupled to at least selectively receive a digital sensor signal representative of one of the N-bits of digital sensor data and operable to selectively transmit the digital sensor signal received thereby.

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.
