Claim 17:
18. The method of claim 17, further comprising:
detecting a second state of a monitored device using a second sensor of the sensor device;
outputting a second sensor signal from the second sensor when the second state meets a second threshold condition;
receiving the second sensor signal at a second tag controller, the second tag controller being configured to selectively connect a second antenna of the sensor device to or from the ground;
selectively coupling or decoupling the second antenna of the sensor device to or from the ground using the second tag controller when the second tag controller receives second sensor signal, wherein:
coupling the second antenna to the ground prevents the second antenna from transmitting a second response RF signal upon receiving the interrogation RF signal, and
decoupling the second antenna from the ground permits the second antenna to transmit the second response RF signal upon receiving the interrogation RF signal;

receiving the interrogation RF signal via the second antenna of the sensor device; and
transmitting the second response RF signal upon receiving the interrogation RF signal and with the second antenna being disconnected from the ground.
