Abstract
Liquefied petroleum gas (LPG) is most widely used all over the world for heating, cooking, vehicle fuel, and so many other fueling purposes. LPG is a highly flammable gas and leakage of LPG occurs major accidents. This paper approaches a smart technique for monitoring the leakage of LP Gas using IoT. In this research, a smart electronic system is developed for monitoring the presence of LP gas, Natural gas, butane, temperature, humidity, and heat index through a webserver. This system can trigger an alarm if the gas leakage is found or any measured parameters exceed the threshold value and also send an alarming SMS to the concerned authority. It can prevent the exploration occurs due to gas leakage. This system is integrated with sensors array which measures the important index related to gas presence and exploration. NodeMCU is a development board having an ESP8266 Wi-Fi chip that is used as a controller unit. The sensors data are fed into a NodeMCU and it imports these data to a website that is accessible from anywhere by using the internet. A 16*2 LCD is connected with the NodeMCU for displaying the sensor's value onsite. A user can enquire about the gas presence by sending SMS also. It's a NodeMCU based low-cost smart system to overcome accidents and gas leakage.
