1. A sensor network having a multiplexing reader and one or more sensor pairs, each sensor pair comprising a transponder and a dedicated reader, dedicated to that transponder, each transponder having at least one sensor, each sensor pair having a wireless interface between the transponder and the dedicated reader, and each of the one or more dedicated readers being coupled to the multiplexing reader, to transmit sensing information from its sensor to the multiplexing reader, the wireless interface being arranged such that the transponder sends the sensing information by modulation with an analog signal representing the information, and the dedicated reader being arranged to receive and recover the sensing information without the need to recognize a digital identifier from its transponder.
