Design a Zigbee-based intelligent light following system. Zigbee nodes connected to human infrared pyroelectric sensors are evenly distributed beside corridors or roads in the system to detect whether there are people in a specific area and transmit the information to the coordinator node. The coordinator node is connected to the main controller PXA270. PXA270 controls the steering of the servo and the lighting device on and off according to the collected information, so that when there are people walking around, the lights move with the movement of people, and when there is no one, the lighting system automatically turns off, thereby achieving the effect of saving energy.
