This paper presents an Internet of Things (IoT)-based power factor monitoring and control system for electrical loads. Modern industries and commercial systems mainly operate with inductive loads such as motors, transformers, compressors, and fluorescent lighting systems. These inductive loads reduce the power factor of the electrical system, resulting in increased current consumption, higher power losses, poor voltage regulation, and reduced efficiency. Continuous monitoring and correction of power factor are therefore essential for effective energy management and improved system performance. The proposed system uses ATmega328 microcontroller, PZEM004 sensor module, ESP WiFi module, relay circuit, and capacitor bank for automatic monitoring and correction of power factor. Voltage, current, power, and power factor values are continuously measured and processed by the controller. Whenever the power factor decreases below the predefined threshold level, relay circuits automatically switch ON the capacitor bank for correction. The measured parameters are displayed on LCD display and simultaneously uploaded to ThingSpeak cloud platform for remote monitoring through internet connectivity.
