abstract = {This paper presents a smart energy monitoring and prediction system designed using the ESP32 microcontroller, calibrated voltage and current sensors, cloud-based IoT communication, and machine learning techniques. The system accurately measures real-time electrical parameters such as RMS voltage, RMS current, instantaneous power, and mains status using a ZMPT101B voltage sensor and an ACS712 current sensor. Special calibration and signal-conditioning techniques are employed to ensure instant response during mains ON and OFF conditions, eliminating residual and false readings. The measured data is transmitted to a cloud MQTT broker and visualized through a real-time web-based dashboard for continuous monitoring. In addition to monitoring, the system incorporates an over-voltage fault detection mechanism using both hardware indicators and software alerts. A machine learning regression model is trained on historical energy data to predict short-term future power consumption, enabling proactive energy management and fault anticipation. The proposed system offers a low-cost, scalable, and intelligent solution suitable for smart homes, industrial energy monitoring, and predictive maintenance applications.},
