The program of this invention (see attached map) is to combine the temperature sensor with electronic label technology to produce an electronic label in the control of temperature (1), and has designed a special read-writer to read the information and automatically drawn the temperature curves during a certain period (2). It can also join with the users' RFID systems (3), and if beyond the temperature range, give an alarm automatically. The features of the system are that the temperature sensor is installed in the electronic label, and a hole is designed on the shell to capture temperature changes effectively. The readr-writer is installed to read and record the information of temperature changes, and automatically draw the curves changed with time and temperature during the period according to the reading information, giving an alarm when beyond the setting range. The system can also join the RFID application system to be used in net. |
