IoT-Based Energy Monitoring System (IBEMS) for Optimizing Power Consumption in University Facilities

This paper presents the development and implementation of an IoT-based Energy Monitoring System designed to optimize power consumption within university facilities. The system leverages real-time current and power readings, transmitted to a cloud-based Firebase database, to monitor energy usage across selected rooms at Caraga State University. Utilizing the ACS712 current sensor and ESP8266 Wi-Fi module, the system provides accurate and reliable data. Users can remotely control the power supply to various rooms via a web-based graphical user interface (GUI), enabling efficient energy management. The system’s ability to switch electrical lines on or off remotely contributes to reducing unnecessary power consumption and lowering electricity costs. Performance tests demonstrate that the current sensor’s accuracy is within $\pm 1.5 \%$, confirming the system’s reliability. While the current study excludes voltage sensors, it highlights the potential for future enhancements to further improve accuracy. This system is envisioned as a significant tool for promoting energy efficiency in educational institutions, with the potential for broader application in other sectors. The results indicate that the developed system can effectively monitor and control energy consumption, contributing to sustainable energy management practices.
