LOW-COST GAS LEAK DETECTOR

Abstract

Due to social isolation due to the coronavirus pandemic (COVID19) the population had to stay for long periods in their homes, culminating in a significant increase in the number of domestic accidents related to cooking gas leaks. Currently, the most modern gas leak detection systems accessible to the population have the ability to identify leaks according to their proportion in relation to the oxygen in the environment, but almost all of these equipment only alert people who are close to the occurrence of the leak, with audible and/or visual warnings. In this sense, the objective of the work was to develop an intelligent device integrated in the Arduino hardware, which detects the leakage of LPG gas (Liquefied Petroleum Gas, which can also be called Pressurized Liquid Gas) and which is capable of acting on the leakage of gas in three levels. The system will aim to ensure the safety of its users and other human beings present in the vicinity of the site, since accidents related to gas leaks cause catastrophic accidents, not only on the site, but also around it, due to the high rate of chance of explosion.
