A Zigbee-based tobacco grading embedded systems is proposed in order to achieve easy installation of the devices and reduce wired communication lines between each device in the station for purchasing tobacco. Introduce several selectable wireless communication way and describe the overview of Zigbee and its advantage. The hardware composition and performance for the system and the working principle of the whole system are presented,highlighting the data transmission and C language realization between center node and tobac-co grading system. Give the running information and content of the send log after transplanting the embedded Linux. The result of the ex-periment shows that the scheme is feasible,and has the advantages of simple structure,high reliability and good real-time.
