Safety gas leakage system based on IoT.

Building fires have become a major growing concern over time. Liquefied Petroleum Gas (LPG) is commonly used for cooking and heating, which is considered a fast flammable gas. The most important damage to LPG lies in its large quantities of leakage inside halls and closed rooms in particular. Gas fires are rapid and spread into very large areas. In this paper, early detection of the LPG leakage is addressed by relying on the technology of the internet of things (IoT). MQ-2 is used to detect gas emissions with a Node-MCU micro-controller supported by Wi-Fi service. The project is characterized by the proposal to turn off the main electrical current supply of the building, aeration of the work-site and it is sending a warning message to the owner via the IoT server. Free server approved to monitor gas leakage cases, where other preventive procedures are taken automatically. The results showed a good response from the proposed system. [ABSTRACT FROM AUTHOR]
