Survey on Real-Time Gas Leak Detection and Prevention System with IoT

Gas leaks, particularly involving LPG, pose severe safety hazards in homes,industries, and commercial spaces, leading to potential explosions, fires, and health risks. Traditional gas leak detection systems often lack automation and remote monitoring, leaving gaps in timely intervention. This project addresses these issues by designing a comprehensive Gas Leakage Detection and Prevention System using IoT. The MQ6 gas sensor is employed for accurate real-time detection of gas leakage, while an ESP32 microcontroller processes the data and triggers a relay module to shut off the gas supply via a solenoid valve in the event of a leak. The system provides local alerts through a buzzer and LED indicator, while displaying gas concentration and leakage status on an LCD display. The integration of the Blynk IoT platform allows users to monitor gas levels remotely and receive alerts on their mobile devices. Key findings from the system’s implementation demonstrate its ability to automatically prevent gas leaks and enable timely responses. The project offers a scalable, cost-effective solutionfor enhancing gas safety, with applications in residential, commercial, and industrial settings. In conclusion, this system significantly improves gas leakage prevention by combining automation, real-time monitoring, and remote access for enhanced safety and control.
