Design and Development of a Smart Motion Detection System Geared Towards Energy Conservation at a State University in Bacolor, Pampanga

Energy waste remains a significant issue in educational institutions, where lights and ventilation systems are often left operating in unoccupied rooms. This study focuses on the design and development of a Smart Motion Detection System implemented in Classroom B103 of the CEA Building at Don Honorio Ventura State University, Bacolor, Pampanga. The system integrates motion sensors, microcontrollers, relay modules, and magnetic contactors to automatically turn off lights and fans when no movement is detected. It supports compliance with national energy policies, including Republic Act No. 11285, Administrative Order No. 15, and the university’s Energy Efficiency and Conservation Unit Policy. A design and development research methodology was employed, supported by quantitative analysis of energy consumption. Comparative data over a 10-day period showed a reduction in electricity usage from 33.91 kWh to 18.5 kWh, marking a 45.44% decrease. System improvements, such as passive infrared sensor recalibration and an SMS notification feature, enhanced reliability and usability. Findings demonstrate that the Smart Motion Detection System is both effective and scalable, offering a practical solution for reducing energy waste in academic settings. The study recommends its wider adoption in other classrooms and public buildings to foster sustainability, reduce operational costs, and support energy conservation goals.
