With new innovations and technologies world besides being facilitated is also subjected to face the threat of major misadventures and disasters. Likewise, Liquefied Petroleum Gas (LPG) is generally used in household for kitchen in general and gas geysers or heaters in winter. Similarly, industries use it for different causes for instance furnace, boiling and get higher production at cheaper rate. Besides, this gas is igneous gas and can cause potential hazard at any time. Hence, in this paper research is made on Internet of Things (IOT) to reduce the chances of such mishaps by presenting a model of microcontroller-based LPG gas detecting and warning system. Furthermore, it explicates the development of self-directed android based mobile device for gas leakage detection that can be installed in all sort of places. Moreover, this device would be containing MQ6 sensor to detect the unwanted outflow and GPS module to locate particular location of leakage what is more Arduino is installed to disseminate information of leakage to different servers like Smartphones, Email and buzzer and shall give display on LCD. Subsequently, it will send the mobile alert to authorized and concerned authorities to take action with in time and there would be buzzer installed. In addition, this device promises automatic working with no need of human interference and assures reliability, efficiency along with cost-effectiveness check-ups of pipeline.
