The document discusses a Zigbee-based solar lighting system that utilizes LDR sensors for automatic control of streetlights, aimed at improving energy efficiency and addressing lighting issues, especially in rural areas. It outlines the use of Zigbee technology for wireless communication, detailing the hardware and software components involved, such as ARM 7 and solar panels. The proposed system is designed to automatically turn lights on and off based on ambient light levels and can also help in detecting faulty lights, thereby reducing maintenance costs and power theft.
