IOT-Based Gas Leakage Detection and Gas Empty Alert System

The increasing use of LPG and other combustible gases in domestic and industrial environments has raised significant safety concerns due to the risk of gas leaks and explosions. This paper presents the design and development of an IoT-based gas leakage detection and gas level monitoring system. The system employs an MQ-135 gas sensor to detect hazardous gases and a load cell to monitor the gas cylinder’s weight. An Arduino microcontroller coordinates these sensors and activates safety responses such as triggering an exhaust fan and buzzer when gas is detected. The system sends real-time alerts via a GSM module and cloud platforms, ensuring remote monitoring and timely notification. It also predicts gas depletion based on usage trends and notifies users for timely refills. With features like multi-channel alerting, cloud dashboards, and predictive analytics, the system enhances safety, efficiency, and convenience. Its low-cost, scalable architecture makes it suitable for a wide range of applications.
