This project is a safety monitoring system designed to detect hazardous gas leaks using an MQ2 gas sensor interfaced with an Arduino UNO. The MQ2 sensor detects gases such as LPG, methane (CH₄), ...
This project is a proactive safety system designed to detect LPG gas leaks and instantly alert users via automated phone calls. Built using an MQ-5 gas sensor, GSM module, and Arduino, it’s ideal for ...
Abstract: This paper describes an LPG gas alarm and auto shut-off prototype built around an Arduino Uno to make homes and factories safer. At its core sits an MQ-2 sensor that tracks gas levels ...
