The output is an analog signal and can be read with an analog input of the arduino. Create a folder, name it data, and add all the certificates into this folder.

You Can Configure The Connection Yourself Regarding.

1) connect the analog input pin 5 of the arduino with the analog out terminal of the mq2 sensor. We have already described the mq3 sensor in a previous tutorial. In this article we are going to learn about interfacing mq2 gas sensor with arduino.

Mq2 Sensor Is A Gas Module And It Is Suitable To Detect Hydrogen, Lpg, Smoke, Co, And Alcohol.

They are sensitive for a range of gasses and are used indoors at room temperature. Connect d0 output pin on the module to digital pin#8 on the arduino and a0 output pin on the module to analog pin#0 on the arduino. // analog input pin that the potentiometer is attached to const int ledpin = 13;

As Mentioned Previously We Can Get Both Analog (Gas Concentration In Ppm) Or Digital (Presence Or Absence Of The Gas) From The Sensor Using The A0 And D0 Pins From The Sensor Respectively.

Connect Your Mq2 Sensor With The Arduino As Shown In The Above Diagram.

Mq2 gas sensor tutorial for arduino, esp8266 and esp32. After we dive into the functionality of gas sensors in general, we build a gas alarm with the mq2 gas sensor that detects smoke and turn on an active buzzer as alarm. Observe the readings on the serial monitor.

The Mq2 Gas Sensor Is Connected To The Arduino Board As Shown In The Schematic Below.

The output is an analog. Afterwards, connect the analog pin of mq2 gas sensor module to a0 pin of arduino uno board. After that connect the gnd terminal of the mq2 sensor with the gnd pin of the arduino.
