Gasguard Autosafe System

Gas leakage is one of the most critical safety hazards in residential, commercial, and indstrial environments. Undetected leaks of Liquefied Petroleum Gas (LPG) or other combustible gases can lead to fire accidents, explosions, environmental damage, and loss of human life. Most conventional safety systems rely on manual inspection or delayed response mechanisms, which are often unreliable and inefficient during emergencies. To overcome these limitations, this paper presents the design and implementation of the GasGuard AutoSafe System, a smart, automated, and cost-effective gas leakage detection and prevention system. The proposed system utilizes MQ-series gas sensors integrated with a microcontroller platform such as Arduino Uno to continuously monitor ambient gas concentration levels. When the detected gas concentration exceeds the predefined safety threshold, the system immediately activates a buzzer and LED indicator to provide local alerts. Simultaneously, a solenoid valve is triggered to automatically shut off the gas supply, thereby preventing further leakage and reducing the risk of accidents. For remote monitoring and rapid response, a module is incorporated to transmit SMS alerts or calling system to users and emergency authorities. The system can be deployed in kitchens, restaurants, hotels, laboratories, and industrial plants The GasGuard AutoSafe System offers a reliable, real-time, and affordable solution for enhancing gas safety and protecting lives and property.
