LPG Leakage Detection and Automatic Booking System

Peoples In recent years there has been rapid development in technology which has made human life easier in several aspects. LPG is a need of every household but many accidents happen every year due to domestic gas leakage, so it should be used carefully. As safety and security is the most important factor we have proposed a LPG monitoring and gas leakage detection system. In our daily life, we don't know exactly the status of LPG gas completion which leads to inconvenience. Along with the leakage detection we also designed feature of sending message to user about the cylinder requirement. MQ-6 gas sensor is continuously measuring the concentration of gases in the air and if sensor reading is above threshold, buzzer is turned on. If temperature increases gradually and reaches threshold value, the exhaust fan may turn on using DC motor and windows are opened using servo motor. Load cell sensor continuously measures the weight of cylinder and when it goes below certain level, message is sent to the user that cylinder booking is required and also automatically sends booking request message to the service provider.
