Smart LPG Leak Detection and Automatic Shutdown System

Real-Time Liquefied Petroleum Gas (LPG) Gas Leakage Detection and Auto Shut-Off System aimed at enhancing safety in environments where LPG is used. The system employs an LPG gas sensor to detect leaks, with an Arduino microcontroller for processing the data. Upon detecting a leak, the system activates visual and audible alerts through an LCD display and buzzer, ensuring immediate awareness of the hazard. A servo motor automatically shuts off the gas supply to prevent potential accidents, while Bluetooth connectivity allows for real-time communication with an Android app, providing users with voice notifications of the leak. Integration of sensors, microcontrollers, and mobile applications offer an innovative and effective solution for gas leak detection, response, and prevention. The system is particularly useful in both residential and commercial settings, where it can significantly reduce the risks associated with gas leaks, offering an extra layer of safety through automated control and real-time alerts. The Proposed automatic system demonstrates the feasibility of integrating various technologies to create a comprehensive safety solution.
