Claim 4:
5. The sensor device of claim 1, wherein:
the sensor device includes a plurality of RFID tags including the first RFID tag, each tag of the plurality of RFID tags including an antenna and a circuit;
a plurality of sensors configured to output sensor signals, each sensor configured to detect an attribute or state of a monitored device, to output a sensor signal representative of when the attribute of the state meets a threshold condition; and
the tag controller is configured to selectively couple or decouple the antenna of each RFID tag of the plurality of RFID tags to or from the ground based on attributes of the sensor signals, wherein coupling the respective antenna of a respective RFID tag to the ground prevents the respective RFID tag from transmitting a respective response RF signal.
