3. Introduction

A gas leak refers to an unintended leak of natural gas or another gaseous
product from a pipeline or other containment into any area where the gas
should not be present. Gas leaks can be hazardous to health as well as the
environment. Even a small leak into a building or other confined space may
gradually build up an explosive or lethal concentration of gas. Leaks of
natural gas and refrigerant gas into the atmosphere are especially harmful
due to their global warming potential and ozone depletion potential. Leaks of
gases associated with industrial operations and equipment are also generally
known as fugitive emissions.

4. Objectives
1. To detect three type gases.
2. To give audio alarm.
3. To give visual alarm.
4. To give mobile SMS.
5. To open an exhaust fan.

14. Outlook of the project.

15. Advantage
1. Low cost.
2. Low power consumption.
3. It also detects alcohol so it is used as liquor tester.
4. The sensor has excellent sensitivity combined with a
quick response time.
5. Able to pass the gases out automatically through
exhaust fan.
6. Able to send SMS to user using GSM technology.
7. When use in vehicle then alcohol detect and turn off
the vehicle.

17. Future Work
1. If we will get any funding then we will upgrade our system
security.
2. In future we can use high accuracy sensors.
3. We will use network booster that our project won’t get any
network issue will happen.
4. In Future we will use AI (Artificial Intelligence) to make our
project smarter than any other devices.
5. We will use IoT in future.

18. Conclusion
GSM based three type gas detector will keep us safe from accident at different times.
Which prevents property damage and Human Injuries. It is very low cost that's why
many poor people can benefit from using it. When gas leakage this gas detector
immediately gives alarm to the users. And try to prevent the dangerous accident by it’s
own using exhaust fan.
