Arduino And MQ2 Gas Sensor © CC0 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.
· In this tutorial you are going to learn about Gas Sensor(MQ2) and the interface with Arduino UNO both in Analog and Digital mode. Theory. Mainly we can say it is a Metal Oxide Semiconductor(MOS) type Gas Sensor. It detects gas on change of resistance of the sensing material, when the it comes nearer to sensor.
· Parts-per-million (ppm) is the ratio of one gas to another. For example, 1,000ppm of CO means that if you could count a million gas molecules, 1,000 of them would be of carbon monoxide and 999,000 molecules would be some other gases. Connecting MQ2 Gas Sensor Module to Arduino UNO. It is very easy if you know how to use Arduino IDE. Wire ...
MQ2 Sensor is a gas module and it is suitable to detect Hydrogen, LPG, Smoke, CO, and Alcohol. It has high sensitivity and fast response time to measure and take the data. Sensitivity can be adjusted by potentiometer behind it:
The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a built-in potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas. MQ-2 sensor
· In today’s tutorial, we are going to understand How to interface the MQ2 Gas sensor With Arduino Uno. MQ2 Gas Sensor Module. MQ2 gas sensor is basically an electronic chemiresistor, a sensing material whose resistance changes when it comes in contact with a gas. It is a sensor used for sensing the concentration of gases in the air such as LPG ...
· 1: Arduino Uno: 1: MQ2 Sensor: 1: I2C Character LCD: Scroll to continue with content This tutorial walks you through building a smoke detector that not only senses smoke and other harmful gases in the air but also reads and displays smoke levels in PPM (parts per million). When the smoke concentration is above 1000 ppm, the circuit triggers a buzzer that can be changed in the code as …
The Gas Sensor is a sensor which detects gas and smoke with concentration between 300ppm and 10000ppm. He can detect butane, propane, methane, alcohol, hydrogen and smoke. He can be only used Inside, at ambient temperature. He has 2 pins for the power, 1 pin for the analogic value and 1 pin for the digital value. For this project, we'll use the ...
· In this tutorial we demonstrate how to interface the MQ2 gas sensor with Arduino to make a simple smoke to my channel: https:///2LiM...
· In this article we will give an example of the MQ2 / MQ-2 smoke / gas sensor program using Arduino UNO. Previously, we discussed a little about what is the MQ2 / MQ-2 smoke / gas sensor. MQ2 or MQ-2 is a sensor module that can be used to detect smoke or flammable gases at concentrations between 200 ppm – 10,000 ppm. Any gas that can be detected by MQ2 includes LPG, …

There are LPG cylinders which are used as a fuel source for the gas stove. Many a times, disastrous accidents take place due to leakage of these cylinders, in these situations we must administer proper care and safety. Keeping this in mind, in today’s post I have worked on MQ-2 gas sensor (FC-22) powered and interfaced with Arduino Uno.

Wiring – Connecting MQ2 Gas Sensor Module to Arduino UNO. Now that we have a complete understanding of how MQ2 Gas sensor works, we can begin hooking it up to our Arduino! Connecting the MQ2 Gas sensor module to the Arduino is pretty easy. Start by placing the sensor on to your breadboard. Connect VCC pin to the 5V pin on the Arduino and connect GND pin to the Ground pin on the Arduino ...
· OK, I understand about the baseline for a gas. What I'm not clear about is that, for example, I set the baseline in my room. The room presumably wouldn't have much H2, …
· Gas Sensor MQ2 Interfacing with Arduino Uno: As you can see I have already connected 3 jumper wires, red is connected with VCC of the sensor module, black is connected with the Ground of the sensor module and white is connected with the analog output(A0) of the sensor Module. I selected A0 for the Smoke or Gas detection as this way I get more control over the MQ2 Gas/Smoke sensor. …
