Intelligent High Voltage Safety Monitoring and Lightning Pulse Detection System Using ESP32 and Firebase Cloud

Intelligent High Voltage Safety Monitoring and Lightning Pulse Detection System Using ESP32 and Firebase Cloud

This project is a real-time electrical safety monitoring system designed to detect high-voltage surges, lightning-induced pulses, and abnormal environmental conditions in electrical installations. The system utilizes an ESP32 microcontroller to continuously monitor temperature, humidity, relay status, and high-voltage fault signals through connected sensors. Whenever a lightning pulse or HV fault is detected, the ESP32 immediately trips the protection relay to isolate the connected load and prevent equipment damage.

All sensor readings and fault events are transmitted to Firebase Realtime Database through Wi-Fi, enabling live monitoring from a web-based dashboard. The dashboard displays real-time temperature, humidity, relay status, total fault count, and detailed fault logs with timestamps. Users can refresh data, export fault records to CSV files, and clear historical logs for maintenance purposes.

The system also includes a buzzer-based alarm mechanism for local fault indication and provides comprehensive system health information such as ESP32 connectivity, sensor status, Firebase connection status, and data synchronization time. By combining IoT technology, cloud storage, and automated protection mechanisms, the proposed system enhances electrical safety, minimizes equipment damage, and provides efficient fault analysis for industrial and power distribution applications.
