Gas Leakage Detection, Prediction & Alert System Using Raspberry Pi & Cloud Computing

5

Abstract Gas leakage is a common problem in various places, including residential properties, industries, manufacturing facilities, and gas stations. For example, LPG (Liquified Petroleum Gas) is a highly combustible gas which can lead to building fire, suffocation or an explosion. Methane explosions, which occur when a buildup of methane gas, a by product of coal, comes into touch with a heat source, are highly prevalent in coal mines. This can lead to coal mine fire and severe life damage. One of the preventive methods to stop this kind of dangerous accidents associated with gas leakage is to install gas leakage detection systems at vulnerable places. The aim of this IoT project is to build a model that can automatically detect, alert and minimize the chances of calamity. The gas sensor which is used in the model detects any type of gas leakage. Once the sensor detects any leakage, it will send the data to the raspberry pi from there it will be uploaded to the cloud. On cloud the sensor data will be analyzed to determine the severity of the situation and actions will be performed accordingly. If the situation is detected as low (no leakage) no action is performed and the device continuously collects the sensor data. If the situation is detected as high (Leakage), then all the concerned persons are notified via MQTT dashboard app, buzzer will go off and the relay is turned on to perform preventive operations. Our model also predicts the air quality index of the surrounding based on the sensor data using Machine Learning algorithm. With the help of this model, we are able to achieve our aim and we are able to reduce the damage as much as possible.

1. INTRODUCTION

There are many different types of gases that play a vital role in human life, and some of these gases are odourless and colourless, therefore they are not detectable by human senses. The majority of people lack sufficient

LPG is the most common gas used in households and industries.LPGconsistsofgasseslikepropaneandbutane. Thesegasesarehighlycombustible.LPGgasisalsousedas propellant,fuelandasarefrigerant.Whentheleakoccurs, it may cause an explosion. The death rate due to LPG gas leakage and their explosion has increased. Therefore, the leakage should be controlled to protect people from danger.

InpastaccidentsliketheBhopalgastragedyonDecember 1984 more than 3000 people were killed when methyl isocyanate was leaked out. Andhra Pradesh's Nagaram The line became rusted in June 2014, resulting in a gas leak, a blast at the Gas Authority of India Limited's plant, and the deaths of 29 persons. So, to protect people from this hazardous disaster we need to upgrade the technologies.

Sensors are crucial part in our model. There are various types ofgassensors suchas MQ2,MQ5 whichareused to detectdifferenttypesofgasinthesurrounding.

This system sounds an alarm when a gas level exceeds a preset threshold and also performs preventive maintenance.

The United States Bureau of Mines investigatedgasin1910,initiallydevelopedbyDr.Walter Snelling, to see if there was any explanation why it dispersed so quickly, and discovered that the vanishing gaseswerepropane,butane,andotherlighthydrocarbons.

Themajorityofthegasesareverycombustible.Thegoalof this planned method was to prevent unwelcome kitchen difficulties. This technology was primarily used to detect gas levels and send individuals SMS alert messages. Gas wastage in the home and industry was also tracked using infraredsensors.

Gas leaks cause a variety of consequences, including financial loss and human life. The environment has a critical impact in human health issues in everyday life. Fire,suffocation,andexplosionrisksarealldeterminedby physical attributes like as flammability and toxicity. The number of people killed by gas cylinder explosions has beenrisinginrecentyears.
