Ogrodut: GSM based Gas Leakage Detection and Ventilation System using Arduino and Servo Motor

With the world moving towards modernized technologies, use of carbon fuels, such as Liquefied Petroleum Gas (LPG) is in reach within users; domestically and industrially. Even in some developing countries, such as countries within the South East Asian belt, natural gas is supplied at a fixed rate with unrestrained amount for usage. With that being said, this increases the probability of wastage; and hence from this kind of wastage of this invisible and odorless gas, comes the chance of accidents. LPG and natural gas is highly combustible and can burn even at some distance from the source of outflow. Most flame related mishaps occur due to the spillage of gas. The project in this paper aims to help LPG user by notifying on any unnoticed gas emission or leakage accident through alarming them as well as creating opportunities for them to take critical and immediate actions; so that the damages to loves and wealth can be avoided or minimized. The proposed gas leakage detection system will detect gas within a certain area using a MQ2 sensor and any moment a gas leakage due to a vital mistake or pipe crack is sensed, it will immediately turn on a ventilation system for the leaked gas to pass out. The system includes a GSM module, which makes the user or owner of the place observant by sending a text message on their phones. In addition to that, in order to maximize the range of the people notified, a buzzer and LCD module is employed so that the residents next door can also be made aware of this mishap.
