IOT Enabled Gas Leak Detection and Safety Automation System

Gas leakage poses a serious safety concern, potentially leading to fire outbreaks, explosions, and severe health complications due to the buildup of toxic gases.Conventional gas detection mechanisms depend largely on manual observation or basic alert systems, which often lack the efficiency for timely action.This project introduces an IoT-based gas leakage detection and prevention system designed for real-time identification and immediate response to hazardous leaks.The system incorporates an MQ6 gas sensor connected to a NodeMCU ESP8266 microcontroller to constantly monitor gas concentration levels.When gas levels exceed a predefined safety threshold, the system triggers a buzzer and LED alerts, shuts off the gas supply via a solenoid valve through user mobile with remote access, and activates a servo motor to open nearby windows for ventilation.With real-time notifications delivered to users, this system offers an intelligent, automated approach to enhance safety and prevent accidents in domestic, commercial, and industrial environments.
