ABSTRACT:
A sensor apparatus (2) has a coil (20) for receiving an electromagnetic wave energy applied from outside, a power supply section (21) for generating an internal power supply from the electromagnetic wave energy, and a sensing circuit (24) having a sensor device mounted thereon. The sensor apparatus receives and decodes a tolerance value intrinsic to the sensor apparatus and set by a configuration/read-out apparatus (1) based on the output of the sensing circuit of the sensor apparatus placed under a prescribed environment, and stores the tolerance value in a nonvolatile memory (23). The sensor apparatus placed under a measuring environment sends out the output of the sensing circuit and the tolerance value to the configuration/read-out apparatus.
