This paper presents a system for monitoring and managing energy consumption in residential and commercial settings. The system utilizes an Arduino UNO microcontroller, sensors (voltage, current, and RTC), and communication devices (ZIGBEE and GSM modules) to collect and transmit energy usage data. An IoT module, specifically the ESP 8266, is integrated into a master device, which continuously updates the sensor values into a database for analysis and monitoring. A real-time LCD display provides immediate feedback on energy consumption, while the GSM module enables SMS communication with the service provider for notifications and alerts. The proposed system offers advantages such as enhanced energy management, remote monitoring and control, and prompt notifications. It finds applications in various areas, including residential energy monitoring, smart buildings, and industrial energy management. The system contributes to energy conservation, sustainability, and cost savings, making it a valuable tool for energy efficiency initiatives.
