This project introduces a smart energy monitoring system using an Arduino, current sensor, LCD display, and IoT module. The current sensor detects real-time current flow, and the Arduino calculates power consumption. Data is displayed on an LCD and also sent to a cloud platform via Wi-Fi for remote monitoring. This low-cost, user-friendly system is ideal for smart homes and industrial setups, enabling efficient energy tracking, usage analysis, and cost-saving power management through continuous monitoring.
