Abstract:

<strong>Gas leakage detection systems are crucial for ensuring safety and preventing accidents in both domestic and industrial environments. The effectiveness of these systems largely depend on the performance of the gas sensors used, which are responsible for detecting gas concentrations. This review evaluates the various MQ sensors employed in gas leakage detection systems, focusing on their capabilities, limitations, and applications. The survey shows that while MQ2 and MQ5 sensors are versatile for domestic environments, MQ4 and MQ6 sensors are more specialized for methane and LPG detectio

Abstract:

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 mod

Konsumen pengguna gas LPG terkadang juga lupa untuk mengecek level gas yang tersedia sehingga yang terjadi adalah kehabisan gas saat sedang digunakan. Begitu juga jika pada system kompor gas terdapat kebocoran dan konsumen yang menggunakan tidak sadar, maka kadar gas yang bocor dapat menyeba

Almost every household and restaurants use Liquified Petroleum Gas (LPG) in their kitchens as it is an essential part of cooking. As important as it becomes it is often difficult to maintain it as there are a lot of difficulties for the users and the igneous gas can cause hazards at any time. The main issue arises when we cannot detect gas leakage in our LPG and there is no automated booking yet. These leakages can cause the life of the user. We can only understand that the gas cylinder is over when it is empty and stops working which is very inefficient for the users. To rectify these issues
