Abstract

Liquefied Petroleum Gas is used for a wide range of
both domestic and industrial purposes. Its use has seen
a significant increase over the years. Unfortunately,
there have also been many casualties resulting from gas
explosions in recent times. Often, there is a news report
of a gas explosion occurring somewhere, whether at
home, in the marketplace or in an industry. Although
these accidental explosions are sometimes beyond
human control, some are due to ignorance, negligence,
or improper care of gas cylinders. Most explosions are
caused by undetected gas leakages which are then set
off to explode with the slightest ignition. Apart from
explosions, fires at homes can also be caused by gas
leakages. This usually results in serious injuries, loss of
property and even sometimes, loss of lives. This project
seeks to provide a smart, budget friendly and easy to
use gas leakage detector system, a better alternative to
relying on the natural way of using the nose, which may
fail and in effect, incur undesirable consequences. The
system employs an MQ2 sensor interfaced with an
ESP8266 Wi-Fi module for sensing the gas in the
atmosphere and displaying an alert message on the lcd.
The Wi-Fi in combination with the microcontroller
module acts as the transmission and processing unit,
allowing for communication over wireless medium.
This way, a user can receive notifications on a mobile
device depending on changes the hardware system
detects in the atmosphere. There is also a buzzer to alert
nearby persons by sound so that they can take the
necessary precautions and actions
