<P>PROBLEM TO BE SOLVED: To obtain a data carrier without power supply and with a temperature and humidity sensitive sensor added for conducting or interrupting antenna coil wiring or memory wiring, by sensing the temperature and the humidity which is not lower than or not higher than predetermined values. <P>SOLUTION: The data carrier with temperature and humidity sensitive sensor is constituted by having the data carrier 2 which communicates with a predetermined interrogator; an antenna coil 1 which can supply power to the data carrier 2; and a temperature and humidity sensitive sensor 3, which senses the predetermined temperature and humidity, turns on/off the power supply, and controls the operation of the data carrier 2 by connecting to the antenna coil 1, without power supply. The connection status of the antenna coil 1, with respect to the data carrier 2, can be varied without power supply on the basis of the temperature and the humidity. As a result, the data carrier with temperature and humidity sensitive sensor, to which the temperature and humidity sensitive sensor 3 is added, which conducts or interrupts the antenna coil wiring or the memory wiring by sensing the temperature and the humidity which is not lower than or not higher than the predetermined values, and the temperature and humidity sensing system can be obtained. <P>COPYRIGHT: (C)2004,JPO |
