Abstract: In embodiments of the present invention improved capabilities are described for an antenna-based detection method and system for sensing an environmental change condition. The method and system is adapted such that the states comprising the environmental change condition are capable of being determined at the location of the detection point utilizing only the magnitude component of the antenna impedance as altered by the discrete change in the environmental condition.
