Real-time monitoring of energy consumption is important for reducing energy wastage and identifying abnormal electrical conditions at an early stage. Conventional energy monitoring methods often require manual observation and provide limited information about energy usage. This research presents an IoT-Based 2-Node Electrical Parameter Measurement and Centralized Visualization System for continuous monitoring of electrical parameters. The proposed system measures voltage, current, power, energy consumption, and temperature using sensors and processes the acquired data through a microcontroller. The measured parameters are displayed locally on a TFT display and transmitted through an IoT module to a centralized monitoring unit, enabling electrical parameters from multiple locations to be monitored at a single point. This multi-node approach provides real-time measurement, visualization, and automatic data transmission, reducing the need for manual monitoring. The experimental results demonstrate that the system can continuously monitor electrical usage and identify abnormal variations such as sudden changes and overload conditions. The proposed system can be applied in educational institutions, laboratories, industrial facilities, offices, and other energy-consuming environments. Future development can include cloud-based data storage, historical energy analysis, automated fault alerts, advanced energy-management features, and expansion to additional monitoring nodes for larger-scale energy monitoring applications.
