IoT Based LPG, Smoke, and Alcohol Detection System with Automatic Power Cut-off

Since the dawn of the industrial age, fossil fuels have driven the wheels of human civilization and have directly and indirectly fueled all major technological advancements of the modern age. Liquefied petroleum gas is a primary fossil fuel that is used as a source of energy in industries, automobiles, and for domestic purposes. In spite of it yielding high calorific value, less smoke, and less soot, it is highly flammable and can burn far away from the source of leakage. The risks of severe accidents, fire, and suffocation can be avoided by implementing a smart gas leakage monitoring and notification system. This paper outlines the design of a smart gas leakage detection system that can detect, alert, and regulate gas leaks automatically. As IoT has become one of the most important technologies of the twenty-first century that can easily communicate with other IoT devices over a wireless network. So, we have developed an IoT-based LPG, smoke, and Alcohol detection system that can cut the power supply automatically to ensure more safety and surety.
