Title:
SENSOR DEVICE, SETTING DEVICE, READING DEVICE, AND ARTICLE ADMINISTRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2001/092830
Kind Code:
A1
Abstract:
A sensor device (2) comprising: a coil (20) for receiving an electromagnetic energy applied from the outside; a power source unit (21) for generating an internal power source from the electromagnetic energy; and a sensing circuit (24) having a sensor element mounted thereon. An allowable value, which is intrinsic to the sensor device and set by a setting/reading unit (1) on the basis of the output of the sensing circuit of the sensor device under a predetermined environment, is received and decoded and is stored in a nonvolatile memory (23). The sensor device under a measurement environment transmits the output and the allowable value of the sensing circuit to the setting/reading unit.
