In the modern society, Liquefied Petroleum Gas (LPG) has been widely used as a cooking fuel in homes, hotels and industries. However in many cases, LPG leakage poses a serious threat to the users and the society. There are several ways to avoid the damage because of the gas leakage but the best way is to place a gas leakage detector nearby the source. Apart from the safety issue, people also find it difficult to identify the amount of gas remaining in the cylinder which causes inconvenience in their work. Therefore this project proposes a flexible and reliable way of detecting the leakage of LPG, monitoring the amount of LPG available in the cylinder and provides the ability to book a cylinder by automatically sending the booking request via SMS to the distributor as required. This system is also capable of sending an alert SMS notification along with a buzzer to users to notify about the leakage to avoid major accidents. The advantage of this proposed system over the existing ones is that it continuously monitor the gas level and also offers quick response to the events and accurate detection of leakage.
