The "Smart Street Light System" project represents a cutting-edge solution to the urban lighting challenges faced by cities today. It leverages advanced technologies like sensors, wireless communication, and data analytics to create a highly efficient and responsive street lighting system. Traditional street lighting consumes significant energy and maintenance resources for municipalities. However, this innovative system can potentially reduce these costs by 50% to 70%. In the center of this system is the smart street light controller, which is mounted on each street light pole. This controller comprises a microcontroller, various sensors, and wireless modules. It intelligently manages LED street lighting based on factors like traffic flow and communicates crucial data between neighboring street lights. Wireless technology facilitates the transfer of data from these controllers to a central base station, enabling real-time monitoring and control. The system operates in two modes: automatic and manual. In automatic mode, it autonomously adjusts the lighting intensity and timing based on traffic and environmental conditions. It achieves this by employing infrared (IR) sensors to detect approaching vehicles and obstacles. When a vehicle or obstacle is detected, the street light illuminates, ensuring safety and energy efficiency. Once the vehicle or obstacle departs, the light extinguishes, conserving energy. The real-time status of each street light, whether it's on or off, is accessible through the internet. This within the core of conveniently monitor and manage street lighting from anywhere, at any time, via an internet connection. The "Smart Street Light" project not only promises substantial energy savings and reduced maintenance costs for cities but also contributes to a safe and more sustainable urban environment.
