An Intelligent Gas Monitoring System with Solenoid Valve and Weight Cell using MQTT

Abstract

LPG is widely used for cooking in many countries due to its accessibility, affordability, and popularity as a source of fuel. When using it, common issues include gas cylinders running out of fuel at prime cooking times, forgetting how much gasoline is actually in the tank, and failing to predict the LPG cylinder's useful life after installation. Leakage can explode if it is not discovered Therefore, a system to ceaselessly monitor this is needed. This study focuses on automatic valve closure when a leak is detected and automatic LPG cycle booking when the level drops below a threshold. The gas sensor, Arduino, and solenoid valve are used to automatically close the valve. The gas sensor detects a gas leak and sends the information to the Arduino, which processes it and activates the solenoid valve. The quantity of LPG using a load sensor to measure (SEN-10245). The sensor's output is linked to an Arduino R3. IFTTT is used to transmit information to users via SMS (short message service), and it also handles automatic booking by sending a message to a gas agency. When LPG leaks, the user is notified with an IOT buzzer and by receiving a message on their mobile device. Additionally, a notification is sent when the level is dangerously low (below 20%). So, by doing this, early and late reservations can be avoided. Consequently, we may avoid unforeseen LPG gas burst accidents in the home by detecting the leak.
