Development of an android-based energy meter reading with load control monitoring

Abstract

In today’s power systems, managing energy efficiently depends on accurate measurement and effective control. While traditional meters do well in basic readings, they often require manual checks, lack real-time tracking, and cannot control loads remotely, making it harder for users to act quickly and manage consumption effectively. This work introduces an Android-based energy meter reading system with built-in load control, combining the reliability of traditional measurement with modern features like automatic meter reading, live data display, and remote load switching through a simple smartphone app. The setup uses voltage and current sensors, a relay module, and an LCD display connected to an ESP32 microcontroller, with IoT communication enabling instant access and smooth user interaction. Testing showed that the system records energy use with high accuracy, manages loads effectively, and provides stable real-time monitoring. By solving common limitations of conventional meters, it offers better efficiency,user convenience, and potential cost savings, supporting a smarter and more sustainable approach to energy use
