Abstract

This study presents the design and implementation of an Internet of Things (IoT)-based electrical energy monitoring system tailored for commercial buildings. With the growing demand for energy efficiency and sustainability, real-time monitoring has become essential for reducing operational costs and improving energy management practices. The proposed system utilizes microcontroller-based hardware (ESP32) integrated with current and voltage sensors to capture real-time electrical parameters such as power consumption, voltage levels, current flow, and energy usage patterns. Data acquisition is achieved through wireless communication via Wi-Fi, with all measurements transmitted to a cloud-based platform for storage, visualization, and analysis. A web-based dashboard and mobile interface provide users with intuitive access to energy usage statistics, historical trends, and anomaly alerts. The system was tested in a mid-sized commercial building, and results demonstrated high accuracy in energy readings, low latency in data transmission, and effective identification of peak consumption periods. This IoT-based approach offers scalability, affordability, and flexibility, making it a viable solution for smart energy management in commercial environments. The findings support the integration of IoT technologies into building energy systems to promote real-time decision-making and reduce overall energy consumption
