Smart Gas Controlling System
Project Area of Specialization Internet of ThingsProject SummaryLiquefied petroleum gas (LPG) is currently the most used gas in our home for cooking purposes. LPG gas is a flammable gas, if leaked it can cause major damage to life and property. Therefore it should be used in safe handling manner and additional care has to be taken in order to prevent any leakage possible. The main features of LPG is that being heavier than air, it do not disperse easily and may lead to suffocation when inhaled. The leaked gases when ignited may lead to explosion. The number of deaths due to the explosion of gas cylinders has been increasing in recent years. Now a days people are having very busy schedule and hence sometimes they forget or don’t get enough time for booking the gas from the gas agency. So it would be much easier and helpful if there was a provision to book the gas automatically. A major amount of gas is being wasted due to the carelessness of consumer’s .Sometimes they forget to turn off the burner which may also could lead to damages. Our proposed topic aims at detection of gas leakage and automatic controlling of gas valve. The smart gas system which provides home safety, detects the leakage of the LPG and alerts the consumer about the leak by a notification through by using android app through Internet Of Things (IOT) and consumer can turn off the gas valve , from anywhere in the world. The additional advantage of the system is that it continuously monitors the level of the LPG present in the cylinder using load sensor and if the gas level reaches below the threshold limit of gas so that the user can replace the old cylinder with new in time and books the cylinder by automatically send a notification to the gas agency. An added feature is that if the users accidently forget to turn off the gas burner, the system will inform by activating an alarm. so the problem of wastage of the energy is solved
Project ObjectivesThe objective of this project is to provide the people a safety device which can help in controlling the SUI Gas levels so that it does not harm anyone in the house. Our aim is to reduce the risks in Kitchen using Internet of Things. The main aim is to propose the design and construction of an SMS based Gas Leakage Alert System. Gas sensor are used to detect gas leakages in a kitchen. With the help of an infrared sensor the issue of gas wastage is also monitored. An alarm goes off whenever the sensor doesn’t detect any vessel over the burner beyond a particular time period
Project Implementation MethodThe proposed system consist of atmega328 and it is interfaced to sensors like MQ2 sensor, load cell, infrared sensors etc. which are the input of the system. Here the wifi-module is interfaced to these which give the ability to communicate with each other. The proposed method takes an automatic control action upon detection of gas.The regulator valve (motor) would be switched off which completely stops the flow of gas leakage. Initialy if there is a gas leakage then the electronic sensor i.e. the gas sensor that obeys the principle of LPG sensor senses any gas leakage from storage, if any leakage sensed then the output of this sensor goes high. This high signal is monitored by the microcontroller and it will identify the gas leakage. If there is a leakage, the consumer is informed through internet in his device and a signal is sent back to the microcontroller to turn off the valve. In this system, a sensor(load cell) is used to monitor the weight of the gas cylinder ,if it goes below a critical value the sensor senses this condition and sends a notification via internet to gas agency for booking a LPG. The object detection sensor is used to detect the presence of any vessel over the burner. If a vessel is not detected over a predetermined time, then an alarm goes off and the consumer is alerted.
Benefits of the ProjectFollowing are the benefits:
-
Gas monitoring systems deliver real-time alerts about the concentration of harmful gaseous in the atmosphere
-
It prevents fire hazards and explosions
-
It also helps in supervising the gas concentration levels
-
Smart gas monitoring system generates real-time updates about leakages
-
The installation of the system is very cost-effective
-
The solution uses advanced data analytics for the improved decision-making process
-
IoT based smart gas monitoring solution can accurately measure oxygen levels
-
House residents can get immediate gas leak alerts on their connected systems
The project is a Hardware and Software integrated system. It uses MQ2 or MQ3 sensors and arduino to detect the gas levels in a house or any given environment. It also connected to a mobile and web application built on react-native and php respictively which will allow the user to monitor the gas and if there is any leakage.
