RFID TAG HAVING TEMPERATURE/HUMIDITY SENSE AND THERE OF OPERATION METHOD

摘要

An RFID(Radio Frequency IDentification) tag with temperature and humidity sensors, and an operation method thereof are provided to check inner environment information of a container by recognizing an inner environment of the container with a sensor unit installed in the container and recording/updating container information with an RF antenna and an RF reader. An automatic power supply unit(120) supplies power automatically to each component. A sensor unit(110) is installed in a container, and includes a temperature sensor(111) and a humidity sensor(112). A sensor processor(130) receives inner temperature/humidity data of the container from the sensor unit. An RF antenna(140) transceives data between an RFID reader(200) and an RFID tag(100). A CPU controls and processes the data transceived with the RF antenna and the sensor processor. A storing part(160) stores data processed in the CPU. The automatic power supply unit is operated in a sleep mode during normal time, and supplies or cuts off the power automatically by changing into an active mode on user setting time.
