Matlab Guidance Based Smart Gas Leakage Detection and Security System Using Analog to Digital Technique

Abstract

The work describing in this paper develops and demonstrates an analog to digital conversion (ADC) technique based an electronic device which is used to detect gas leakage using mechanical sensors at households, industries, vehicles, gas stations etc. where detection of gas leakage is an important issue to avoid any uncertainty. The device consists of a processing section which takes input, processes it and provides output. Corresponding to this output, it starts exhaust fan and light emitting diode (LED) is on, if concentration of gas exceeds a certain level, starts buzzer (alarm), switch off the gas power supply and notifies the consumer by sending an alert message through the monitoring computer. The gas concentration level for a particular operational area will be stored in Matlab "Database Explorer Tool" in order to get an overview of gas status of this area for future analysis such as probability to take accident and so on.

“…Depending on the output information, it then starts a fan and activates a light-emitting diode; if the concentration of the gas surpasses a certain level, it then activates the buzzer, while also switching off the gas power supply and informing the relevant parties by sending an alert message via the monitoring computer system. The gas concentration level for a particular operational area will be stored in the Mat lab "Database Explorer Tool" to make a summary of the gas eminence of this environment or area available for scrutiny, to inform any risk assessment [8].…”

Liquefied petroleum gas monitoring and leakage detection system using nodemcu ESP8266 and wi-fi technology

“…Hossain and colleagues [4], implemented a Matlab Guidance Based Smart Gas Leakage Detection and Security System Using Analog to Digital Technique and made use of MQ-5 and three features in place for notification purposes. These notification features included an audible alarm through the use of a buzzer and two visible means, via an LED and an LCD display.…”

“…In terms of odour or smell LPG is odourless but an odorant (i.e. a chemical with a pungent smell) called Ethanethoil is added to the gas to make it easily detectable by the human sense of smell or a gas detection sensor [1,4]. LPG is used for various applications such as for domestic fuel, industrial fuel, automobile fuels, in refrigerators and many more and is usually preserved in compressed air tight steel vessels [2][3].…”
