This document summarizes a research paper titled "LPG Leakage Detection and Smart Gas Booking System". The paper proposes a system that uses an MQ-2 gas sensor to detect LPG gas leaks and an Android application to automatically book new gas cylinders. When the gas level drops below a threshold, a notification is sent to the user via SMS. The system aims to improve safety by detecting leaks and reduce user workload by automating the gas booking process. It was developed using Arduino Mega and interfaces gas sensors with an Android application. The system provides both leakage detection and automatic gas booking capabilities.
