IoT-Based Energy Efficient Smart Railway Station Lighting System using STM32

The proposed system successfully demonstrates an IoT-based intelligent lighting solution for railway stations that enhances energy efficiency and automation. By integrating STM32 microcontrollers, PIR and LDR sensors, and LoRa communication, the system ensures reliable and intelligent lighting control. The incorporation of solar power and battery management promotes renewable energy utilization and reduces dependency on grid electricity. Real-time monitoring and control through the ESP32-based web dashboard enable efficient management from remote locations. The system achieves automatic day/night operation, motion-based illumination, and energy consumption tracking for optimized performance. It reduces manual intervention, operational costs, and unnecessary energy wastage. The modular architecture allows easy scalability across multiple railway platforms. Data logging and analytics enable performance assessment for long-term sustainability. Overall, this project contributes to the development of a smart, sustainable, and eco-friendly railway lighting infrastructure aligned with modern smart city goals.
