RFID SENSOR TAG WITH ON-BOARD PROCESSING

摘要

A tag (10) for attachment to a container or similar package being shipped and/or stored includes a central processing unit (CPU) (12), a timer (14), a crystal resonator (16) connected to the timer, a measuring block (18) connected to the CPU, one or more sensors (26) connected to the measuring block, a communications block (20) connected to the CPU, a feedback block (22) connected to the CPU, and an EEPROM (24) also connected to the CPU. In use a sensor senses environmental changes and the CPU processes signals received from the sensor and stores processed data for later retrieval. When required, the CPU communicates such processed data via the communications block to an RF reader for analysis and use.
