ABSTRACT:
Gas leakage in industrial, commercial, and residential environments poses a significant threat to human safety and infrastructure due to the extensive use of LPG, methane, butane, hydrogen, alcohol vapours, and other flammable gases. These gases are often colourless and odourless, making early manual detection difficult and unreliable. Undetected leakage may lead to fire hazards, explosions, respiratory disorders, and loss of life and property. This paper presents the design and development of a low-cost, portable embedded safety system named Smart Nose for Hazardous Zone, capable of detecting hazardous gases and generating immediate alarm alerts. The proposed system integrates an Arduino Uno microcontroller with an MQ-2 gas sensor and a buzzer alarm, powered by a battery source to ensure portability. The system continuously monitors ambient gas concentration and triggers an audible warning when the detected level exceeds a predefined safety threshold. The developed prototype is suitable for deployment in households, laboratories, fuel stations, chemical industries, and confined hazardous environments, offering an economical and effective solution for real-time gas leakage monitoring.
