In this paper, the authors study human body detecting using sensor and design LED (Light Emitting Diode) control system based on star network topology of ZigBee. The human body detecting information using PIR sensor is transmitted to the status monitoring system, and the management system controls the LED lighting devices based on transmitted information. The information and control signals are transmitted using ZigBee network. The structure of the proposed LED control system is suitable for energy-saving because the LED lighting devices are controlled by area.
