Intelligent Security & Safety System for Colleges & Industries

Gas leakage is a serious problem and nowadays it is observed in many places like residences, industries, colleges and vehicles like Compressed Natural Gas (CNG), buses, cars, etc. Liquid petroleum gas (LPG) is highly inflammable and can burn even at some distance from the source of leakage. Gas leakage leads to various accidents resulting in both material loss and human injuries. Home fires have been occurring frequently and the threat to human lives and properties has been growing in recent years. The risks of explosion, fire, suffocation are based on their physical properties such toxicity, flammability, etc. The number of deaths due to the explosion of gas cylinders has been increasing in recent years. The Bhopal gas tragedy is an example of accidents due to gas leakage. A gas leakage detector becomes vital and helps to protect people from the dangers of gas leakage. A number of research papers have been published on gas leakage detection techniques

In this project gas leakage is detected by the gas sensor, the user is alerted about the gas leakage through SMS. This is a low-cost advanced sensor-based gas leakage detector, alert system. The system is very efficient, user friendly, portable, small in size and cost effective.
