A radio frequency identification tag device having a sensor input which modifies a tag data word bitstream read by an interrogator/tag detector. The sensor input may be a switch contact(s), digital and/or analog. The sensor input may be voltage, current, pressure, temperature, resistance, acceleration, moisture, gas and the like. Power from the radio frequency interrogator/tag reader may be used to power the circuits of the radio frequency tag device, which in turn may supply power to any sensor connected thereto.
