An IoT-Based Smart Solution for Preventing Domestic CO and LPG Gas Accidents

Abstract

Gas monitoring systems have turned into a key feature in many applications in different fields, such as medicine, industry, and environmental monitoring. Accidents involving gas leakage generate massive costs and deaths, where carbon monoxide (CO) and liquefied petroleum gas (LPG) are the main causes of domestic accidents. They could be avoidable with smart gas sensors integrated with other smart devices through the Internet of Things (IoT) paradigm. This paper focuses on the design and construction of a smart multi-gas plug-and-play sensor to avoid accidents in smart environments involving CO and LPG. This device is ready to connect on an IoT solution. It uses the standard IEEE 802.15.4 to communicate with a border router responsible to make the data available to other devices. The data will be sent to a middleware granting that other smart devices on the same context can access the information and make the correct decisions. The created prototype was evaluated, demonstrated, and validated, and it is ready for use.
