Classification: CPC G  H | IPC G

Claim 14:
15. The method of claim 12, wherein:
the sensor device includes a plurality of RFID tags, each tag of the plurality of RFID tags including an antenna and a circuit; and
selectively decoupling the antenna of each radio-frequency identification (RFID) tag of a first subset of a plurality of RFID tags from the ground and coupling the antenna of each RFID tag of a second subset of the plurality of RFID tags to the ground based on attributes of the sensor signal, wherein:
coupling the antenna of a respective RFID tag of the second subset of the plurality of RFID tags to the ground prevents the antenna from transmitting a response radio frequency (RF) signal upon receiving an interrogation RF signal, and
decoupling the antenna of a respective RFID tag of the first subset of the plurality of RFID tags from the ground permits the antenna of the respective RFID tag to transmit the response RF signal upon receiving the interrogation RF signal; and

transmitting the response RF signal from the first subset of the plurality of RFID tags upon receiving the interrogation RF signal.
