A Comprehensive Review on Gas Leakage Monitoring and Alerting System using IoT Devices

Over the past three decades, gas leakage is a major problem in the households, hotels, street shops, industries, apartments etc. The number of deaths due to the explosion of gas cylinders has been increased in recent years. The main idea of this paper is to compare different articles worked on the gas detection, to save people lives and their property from the fire accidents. There are several methods to stop the accidents due to the gas leakage that is to install the gas leakage detection system which can automatically detects the gas and helps to stop the gas leakage. The gas detection system detects the LPG, using gas sensors and to monitor temperature in different places. The gas detection system is built using Gas Sensor, Arduino Uno and some output devices. Due to this gas leaking the houses, apartments, industries, big buildings will be in risk because of the fire exposures. Mainly, the gas detection system is used for sending SMS to the user or authorized person that he can take immediate actions like turning off the gas valve from the cylinder and call to the fire station while fire is exposing. When the gas is leaking the buzzer gives a beeping sound that indicates the fire is detected. This system opens the windows, doors automatically when the gas is leaking and then GSM alerts the users that the gas is leaking by sending a notification to their mobile. Mostly fire accidents occurred because of the poor quality of rubber tube in gas cylinders. The gas supply from regulator to the burner may be on even the regulator is in off condition due to blocks in burner or leakage of gas pipes. When the gas leakage goes high it turns ON the LED to indicate and makes an alarm with the help of buzzer. Most of the system used 16×2 LCD display for this problem. An LCD displays the gas leakage result. This paper discussed about the future problems due to the gas leaking and the development in gas leakage.
