Abstract: The increasing demand for electrical energy and the need for efficient energy utilization have emphasized the importance of real-time electricity monitoring and management systems. Conventional electricity meters rely on manual readings, which are time-consuming, prone to human error, and lack real-time visibility of energy consumption. To overcome these limitations, this project presents the design and implementation of a Blynk-enhanced wireless smart energy meter with cloud-integrated energy management. The system utilizes an ESP32 microcontroller as the core processing unit, interfaced with a ZMPT101B voltage sensor and an SCT-013 current sensor to measure real-time electrical parameters such as voltage, current, power, and energy consumption accurately. The measured data is transmitted wirelessly to the Blynk cloud platform using Wi-Fi connectivity, enabling remote monitoring through mobile and web applications. Cloud integration ensures secure data storage, real-time visualization, and historical data analysis, allowing users to track consumption trends and make informed energy-saving decisions. Instant alerts and notifications further enhance system functionality by indicating abnormal power usage or system faults. The proposed system minimizes human intervention, improves billing accuracy, and promotes energy conservation. Its low-cost design, wireless operation, and user-friendly interface make it suitable for residential and small-scale industrial energy monitoring applications.
