Gas outpouring could be a major drawback with industrial sector, residential areas and gas driven vehicles like CNG (Compressed Natural Gas) buses, cars etc. one in every of the preventive methods to prevent accidents connected with the gas outpouring is to put in a gas outpouring detection device at pervious places. The aim of this project is to develop such a tool which will mechanically detect and stop gas leakages in those pervious areas. The system detects the outpouring of the LPG (Liquefied fossil fuel Gas) using a gas sensing element and uses the GSM to alert the person regarding the gas outpouring via SMS. once the LPG concentration within the air exceeds a preset level, the gas sensing element senses the gas leakage and also the output of the sensing element goes LOW. this is often detected by the microcontroller and also the junction rectifier and buzzer are turned ON simultaneously. The system then alerts the client by causing an SMS to the desired mobile-phone.
