Enhancing Energy Efficiency: Performance Analysis of a Smart Lighting System for University Lecture Rooms

With the growing emphasis on sustainability and the need to reduce greenhouse gas emissions, efficient energy management in lighting systems has become increasingly critical. This study proposes an intelligent classroom lighting system that integrates Passive Infrared (PIR) and Light Dependent Resistor (LDR) sensors with a mobile application for real-time monitoring and class scheduling. The system dynamically controls lighting based on occupancy and luminance levels, even when schedules are predefined, while the mobile application provides remote access to energy usage data, including total consumption and lighting duration. Experimental results show that the system operates reliably under varying conditions and yields significant energy savings. Overall, the proposed solution enhances user accessibility, reduces unnecessary energy usage, and demonstrates strong potential as a sustainable energy management tool for educational environments.
