Gas leakage and smart detection system

Gas leakage is a critical safety concern that poses severe risks, including explosions, fires, and health hazards, in industries, residential areas, and vehicles. Detecting and mitigating gas leaks in a timely manner is essential to prevent life-threatening incidents and property damage. This research presents an advanced gas leakage detection and prevention system utilizing Arduino Nano, ESP8266, and Blynk IoT for real-time monitoring, automated alerts, and safety controls. The system incorporates an MQ-6 gas sensor to detect LPG gas leaks, displaying gas concentration levels in PPM on an LCD screen. When a hazardous concentration is detected, the system immediately activates an alarm, sends real-time notifications via the Blynk IoT platform and website, automatically shuts off the gas regulator, and trips the electricity supply to prevent further escalation. Designed for residential, commercial, and industrial applications, this cost-effective and highly reliable solution enhances safety by providing continuous monitoring, rapid response, and automated preventive measures.
