Abstract
Gas or liquefied petroleum gas (LPG) is a chemical substance resultant from petroleum and could be dangerous in industrial
places or those that deal with this substance. Gas leakage causes many health issues. So, to prevent such catastrophes and in
order to maintain a clean air environment, the workspace atmosphere should be frequently monitored and controlled. The
proposed monitoring gas leakage detector system is based on Internet of Things (IoT) technology. NodeMCU ESP8266 Wi-Fi
is used to be the microcontroller for the whole system. The combustible gas sensor (MQ2) is used in order to detect the presence
of methane (CH4) and carbon monoxide gas (CO). MQ2 sensor will detect the concentration of the gas according to the voltage
output of the sensor and the ESP8266 will send the data reading from the gas sensor to Blynk IoT platform over an IOS phone;
data visualization is done using Thingspeak IoT Platform. Besides, a fan will immediately work upon the leakage occurs along
with an alarming buzzer.

KEYWORDS: IoT, Gas leakage, Blynk platform, Thingspeak, LPG, Alarm system.

I. INTRODUCTION LPG consists of a mixture of propane and butane which
is a highly flammable chemical. It is an odorless gas due to

Liquefied Petroleum Gas (LPG) was first discovered in In this research, a computer program running online was

day by day. However, when LPG is leaked, it may cause through the Blynk application which is based on the IoT
