Liquid petroleum gas (LPG) is a fuel that is commonly used in household and commercial settings, it can be dangerous if not handled appropriately. The goal of the "LPG Leakage detection and disaster prevention system" project is to develop a comprehensive method for detecting LPG gas leaks and preventing potential disasters. The project makes use of a buzzer, a DC motor, a water pump, a MQ2 gas sensor, and a fire sensor, among other parts. To give real-time notifications over the internet via the Telegram API, an IoT application based on the ESP32 microcontroller is also included. The MQ2 gas sensor, which is in charge of detecting the presence of LPG gas, it serves as the system's primary input. When a gas leak becomes apparent, the system activates the buzzer and the DC motor to ward off any LPG gas that may be present in the environment and notify the user of the potential risks. This makes it possible to take immediate measures to reduce the risk of a gas explosion. This project also covers the potential for fire outbreaks unrelated to gas leaks in addition to gas leak detection. A fire sensor is incorporated into the system to address this problem. If a sudden fire is detected, the fire sensor triggers the water pump, representing a sprinkling system designed to extinguish the fire promptly. This approach enhances the safety measures and ensures the protection of life and property. The ESP32 microcontroller is used to create an IoT application that will improve the system's functionality. Through this application, the system can be remotely monitored online. The Telegram API notifies the user's device when there are fires or gas leaks. User’s will have the ability to get real-time notifications even when they are not physically present at the system's location, so disaster prevention measures can be taken in a timely manner.
