<p><P>PROBLEM TO BE SOLVED: To allow a sensing system, which includes a reader-writer and an RFID tag, to obtain sensing data at a place where an electromagnetic wave from the reader-writer hardly reaches by stable radio communication. <P>SOLUTION: The sensing system includes a sensor 30, sensor 40, reader-writer 1, RFID tag 10 and RFID tag 20. Each sensor receives power supply through each power supply cable, and outputs sensing data through each communication cable. The reader-writer 1 includes a communicating part 2, the RFID tag 10 includes a storing part 14 for storing electromotive force caused by an electromagnetic wave transmitted from the communicating part 2, and feeding the power to each sensor, a control part 13 for acquiring the sensing data from each sensor, and a communicating part 12 for transmitting the obtained sensing data to the reader-writer, and the RFID tag 20 includes the same configuration as that of the RFID tag 10. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
