A Gas Leakage Detector Using IoT

Abstract

Propane and butane are the two sources extensively in domestic and commercial purposes for various applications ranging from industrial sector to household usages. The usage of these sources mandatorily requires safety precautions to be followed to avoid any hazardous impact. This is due to the gas's volatility and the potential for leakage, which increases the risk of a detonation or fire. This could be avoided or can be prevented by means of early detection that could sense the leakage of gas in a very simplified version, easily identifiable by all age groups of peoples. This research focuses on a prototype system in the first phase that simulates a gas leak in a confined space. The presence of leaked gas in the confined space is traced by the sensor (MQ 6) which in turn sends the traced signal to Arduino micro controller. The test results show successful detection of gas leakage followed by activation of warning message to the designated number. However, based on performance it is found that the system works efficiently in closed space when compared to open space. In open space due to dilution of gas, the detection of content is slower thereby resulting in time delay. In the second phase, the concept of Internet of Things (IoT) is implemented in this system using various devices that are networked together. The use of internet access allows the sensors to exchange data with one another. This paper concentrates on secure kitchens in IoT-enabled smart homes. A regulator and LPG cooker with knobs that regulate the flow are provided for safety in the home gas connections. Gas leaks can be dangerous, particularly in enclosed spaces. A safety system with a strong ability to identify leaks is necessary in these circumstances.
