The increasing consumption of electrical energy remains a significant concern due to its substantial impact. Excessive electrical energy usage not only leads to higher costs for consumers but also contributes to environmental issues. The prototype of the electrical energy consumption monitoring system is designed to provide precise real-time monitoring of energy usage and enhance power factors through capacitor banks, utilizing Internet of Things (IoT) technology. This prototype uses a PZEM-004T sensor to measure electrical parameters, including Voltage, Current, Power, Frequency, Energy, and Power Factor, which is controlled by an ESP8266 microcontroller. The system features an OLED display for direct monitoring and a Blynk application for remote monitoring. Testing and implementation results indicate a very low error margin, less than 0.05%, and demonstrate an improvement in the power factor. These findings confirm that the IoT-based power consumption monitoring system functions effectively, making it a viable solution for managing energy consumption and optimizing power factors. Another result was that power factor improvements at the load resulted in a significant improvement in power factor, as well as a substantial decrease in reactive power. The implication of this system is its ability to help homeowners monitor and control their energy use in real-time. The novelty of this work lies in its integration of low-cost hardware with local and remote monitoring, combined with an automated capacitor switching mechanism that does not require manual intervention. Future developments could expand the system to support three-phase electricity, incorporating automatically adjustable variable capacitors. © (2025), (Insight Society). All Rights Reserved.
