In this tutorial, we are going to learn how to use Arduino and MQ2 gas sensor to check the air quality by checking the concentrations of LPG, smoke, alcohol, propane, hydrogen, methane and carbon monoxide, or other flammable gasses.

Jan 10, 2024 · Learn to make a simple gas sensor with Arduino UNO!

Apr 1, 2022 · MQ-2 Combustible Gas Sensor with Arduino UNO – Connection Diagram. Now that we have complete understanding of how the MQ-2 gas sensor works we can connect all the required wires to Arduino uno. This section of the article will be divided into two parts, one shows analog output and another one shows the digital output.

Mar 15, 2018 · The Grove Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4 and CO.

This guide will show you how to use Arduino UNO R4 and MQ2 gas sensor to monitor air quality by measuring levels of LPG, smoke, alcohol, propane, hydrogen, methane, and carbon monoxide, among other flammable gases.

A simple gas sensor is made up of very sensitive semiconductor material and it is SnO2. The conductivity of this material changes the concentration of the gas present around it. Higher the gas content present, the higher is the conductivity of that material. the circuit diagram is very simple to understand and it is like below
