It was the only cause of many accidents in the past. The purpose of this project is to detect a gas leak and prevent the accident and blocking of gas leaks in vulnerable areas. This includes the MQ6 gas sensor which is used to detect gas leakage in home and industry and is also very much suitable for detecting LPG, i-butane, Hydrogen, Methane, Smoke and Alcohol, etc. But it does not indicate the exact gas concentration. It only illustrates the trend of gas concentration in a suitable error range. This device automatically takes precautions. And even turns off main supply in some time to avoid accidents. And also include the WiFi module to take necessary action immediately by sending an alert SMS to the owner.
