The Study of Auto Recogniton System by Using Zigbee

In this paper, we study the design and implementation of an auto recognition system by using wireless sensor node. RFID system has a limited communication range and communication network is damaged, it is impossible to communicate. Therefore, easy installation and low cost wireless system are required in an area where the installation of communication between RFID system and monitoring system is difficult, or a portable RFID system is installed. The auto recognition system in this study is implemented by the combination of 13.56MHz RFID system using MLX12115 RFID chip of Melexis company and wireless sensor node system using CC2420 Zigbee chip of Chipcon company. As a result, we develop an auto recognition system which makes it possible to get tag's information wirelessly. Also, it has a simple circuit structure and is small in size.
