LPG gas is like combination of Propane and Butane gas, they both are strongly inflammable in nature. So in order to it is combination of both the gases and other components so it more dangerous when it is leaking comparison of Propane and Butane. LPG gas is used to cook food, boil water, etc. The major idea is to protect smart city house when gas will leak because in smart cities there are building which contain n number of floors and each floor have many flat. So if one flat gets fired so it will not stop with one flat, so gas will spread out and it flame many flats also. So in order to prevent this accident we use this system. Actually this problem occurs when people may have a low sense of smell and in such cases they cannot able to sense gas or other thing is when person is outside of his house and gas is leaking inside the house.

The biggest example for gas leakage is Bhopal gas tragedy. That accident is the world’s biggest gas leakage accident. That was the cause of thousands of death. Gas name is methyl isocyanate (MIC) gas. In this kind of situation this system can use that sense gas of any type and that particular time alarm will rung and one attention message will send to registered mobile number.

MQ2 gas sensor

Gas sensor is a sensor which will detect gas. It will detect gases which are released when fire is Arduino Nano Boarded like carbon dioxide, carbon monoxide and many more. When any gases will be detected the sensor will give value as one, if no particular gas is detected it will give value zero. This combination of zero and ones will be used to detect fire. The gas sensor will particularly detect the gases that are released when fire is detected. Here are 4 Pin which are connected with Arduino. 5V, GND, AO and DO. 5V is input voltage is connected with Arduino 5V. GND is ground is connected with Arduino GND. AO is analog input is used to take analog input connected with Arduino A0 to A7. DO is Digital input is used to take digital input connected with Arduino D0 to D13. Only one pin is required either AO or DO.

Sim 900A

Sim900A is used to send message to registered mobile number when Arduino send command to this module. It also contains one more functionality called GPS. So user knows the system location as well or it is traceable also. It takes +5V input and 1 amp. It having 4 connection pins RX, TX, GND and 5V. RX is connected with Arduino TX. TX is connected with Arduino RX. GND and 5V are connected with Arduino GND and 5V. Then only message will send. RX and TX are also called Serial communications.

Arduino Nano

Arduino Nano is heart of the system. Arduino having its own microcontroller the take care all the process. It also having memory RAM that stores user written algorithm. All the things are connected with Arduino Like gas sensor, buzzer, Sim 900A module etc. Inputs are coming from sensors and send it to Arduino. Arduino apply user written algorithm on input and show the output from output devices.

Block diagram of System

Three things are connected with Arduino one is sim900A module, second thing is MQ2 gas sensor and third thing is input which is coming through charger.

Conclusion

The system is used to detect and prevent the leakage of LPG gas that uses in home. The idea behind is to secure the smart cities as well as develop smart villages. If person is outside of the home and gas leak at home then it will send message to mobile and user can send again message to system then it will shut down the system and also like in CNG based auto, buses, cars etc. this system can use and we the help of GPS location can be founded.

Gas leakage problem and it’s prevention

Now days in smart city gas pipelines are fitted everywhere. So gas leakage is the biggest problem is rapidly increase day by day with city and other places also. So to overcome with this problem we can install a remote gas leakage detection and control device at particular place
