Gas leakage from combustible gases such as LPG and methane poses serious risks to human life and property. This paper presents an IoT-based gas leakage detection system using an ESP8266 microcontroller and MQ-2 gas sensor for real-time monitoring. The system continuously measures gas concentration and sends data to a mobile application through the Blynk platform. When the gas level exceeds a predefined threshold, a buzzer is activated and instant alerts are sent to the user. An LCD display is also used for local status indication. The proposed system is cost-effective, reliable, and ensures quick response to hazardous situations. It is suitable for applications in homes, industries, and smart safety systems.
