ABSTRACT
Gas leakage is a major problem with industrial sector, residential premises and gas powered vehicles like CNG (Compressed Natural Gas) buses, cars etc. One of the preventive methods to stop accidents associated with the gas leakage is to install a gas leakage detection device at vulnerable places. The aim of this project is to develop such a device that can automatically detect and stop gas leakages in vulnerable areas. The system detects the leakage of the LPG (Liquefied Petroleum Gas) using a gas sensor and uses the GSM to alert the person about the gas leakage via SMS. When the LPG concentration in the air exceeds a certain level, the gas sensor senses the gas leakage and the output of the sensor goes LOW. This is detected by the microcontroller and the LED and buzzer are turned ON simultaneously. The system then alerts the customer by sending an SMS to the specified mobile phone. Gas leakage leads to various accidents resulting in human injuries and/or loss. The present work aims at designing a system that detects gas leakage and alerts the subscriber through an alarm and sending SMS on user mobile phone and turning off the gas supply valve as a primary safety measure. The designed system, more like a First Aid, automatically uses a normally closed solenoid valve for shutting off of the gas valve before calling for help via visual display and audible alarm to those within the environment. The system prototype is constructed and when a small amount of LPG is leaked near the system, the system sensor detects the leakage and sends the SMS to housemates and activates the alarm and switches on the exhaust fan and prevents the flow of gas using a solenoid valve. The LabVIEW and an Arduino are the programming tools used for this system. LabVIEW is used to monitor the data continuously.
