Abstract: A wireless sensor system identifies a single event in a wireless link. In an embodiment, the wireless sensor system includes an interrogator comprising an oscillator, a power amplifier, an antenna, and a detection circuit. The wireless sensor system also includes a sensor tag. The interrogator and the sensor tag are adapted to inductively couple the antenna and the sensor tag. The detection circuit detects a signal across the antenna, and the single event changes the signal across the antenna. In addition, the detection circuit provides the identification of the single event by detecting the change in the signal across the antenna.
