Internet of Things based Automatic LPG Gas Leakage Detection and Prevention System

This study offers an Arduino-based LPG gas leakage detection system with an automatic shut-off regulator to offset gas leak-related accidents. The proposed system uses an MQ-2 gas sensor to sense leaks and automatically activates a solenoid valve to close gas flow. According to experimental findings, the system has a rapid response time of 3 seconds and a detection rate of 95% in controlled environments, largely mitigating fire hazard risk. Moreover, an IoT-based warning system offers real-time warnings, enhancing user consciousness and responsiveness. The research identifies a cost-effective and reliable solution to maximize gas safety in domestic and industrial application. This system will activate an effective alarm immediately it detects leakage in the gas and provides critical early warnings to occupants. In addition, it automatically shuts off the main gas supply, thus preventing possible production of more hazards. A system like this is well needed because detecting LPG leaks that are flammable is often very challenging, which can easily lead to the damage of property or physical harm to individuals. Besides, leaks, especially those that go unreported, and improper covering of hoses and regulators point out the importance of automating safety solutions.
