This project uses sensors to monitor indoor natural gas on the basis of Arduino, and will sound the alarm if the gas leak exceeds the limit. MQ-4 Natural Gas Sensor Experiment Based on Arduino Project tutorial by Andrew85
· Gas Sensor MQ2- In this Tutorial, you will learn how to use the Smoke/Gas sensor Mq2 with Arduino. MQ2 Sensor is one of the most commonly used Sensors throughout the world. This Sensor is most commonly used for the Smoke and Gas detection.
We will make it in our code that if the sensor outputs a voltage above a certain threshold, the buzzer will go off, alerting a user that smoke has been detected. These are all the physical connections in order for our circuit to work. Code for the Arduino MQ-2 Smoke Sensor Circuit. Being that we've just gone over the circuit schematic for the smoke sensor circuit, all we need know is the code ...
· Connect analog pins: Afterwards, connect the analog pin of MQ2 gas sensor module to A0 pin of Arduino Uno board. Basically, Smoke A0 pin is the input pin. Connect buzzer to Arduino Uno: Finally, connect positive terminal of the buzzer to Pin 11 of Arduino, and negative terminal to GND of Arduino. This means buzzer pin is the output pin. Result Diagram (Pinout) The above arrangement …

This code is simple and easy to understand. It is configured with 2 LED’s which acts as visual indicators. Led’s are optional. Copy the below code in Arduino …
· Code. You can adjust the variable sensorLimit with a different threshold value. Wrapping up. We have learnt about the MQ2 gas sensor module and how to use it with Arduino Nano. Check for more DIY projects here. Thank you for reading and supporting us.
· muthusam: I need ARDUINO code for MQ2 sensor that will give output for all the gases that can sense by mq2 sensor(CO,CH4,ALCHOCOL,PROPANE) :o :confused: That sensor indeed can only measure the total of such combustible gases present - it can not provide info on the individual components. See data sheet for sensitivity to the various gases. If you can be sure within your setup …
You should try experimenting with your MQ2 smoke gas sensor to set the threshold value. The LCD should print the Welcome message once the Arduino Nano is powered up. After 2 seconds, the LCD should display "Smoke Detector" in the first row and "MQ2" in the second row. The display should be cleared after 2 seconds.
