How To Make Mq2 Gas Sensor Arduino Project

How To Make Mq2 Gas Sensor Arduino Project. Also, this mq2 sensor can measure the amount of lp gas, smoke, carbon monoxide, and methane in the air. So, for this example, you’ll need:

MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32 from diyi0t.com

Adding a simple mq2 gas detecting sensor module to the project makes it a combined smoke + gas detector device. Connect the vcc pin of the sensor to the 5v of the arduino. This module is provided with male header interface and can be easily interfaced with arduino/mega using male to female type jumper wires.

They are sensitive for a range of gasses and are used indoors at room temperature. Mq2 is basically a general purpose gas sensor (similar to mq5) which can sense a broad range of gases like lpg, butane, methane(ch4), hydrogen and in addition to these gases mq2 is sensitive to smoke as well.

Jumper Wires And A Small Breadboard

Connect and interface mq2 gas smoke sensor with arduino uno using the schematic given above. The resistance of the sensor is different depending on the type of the gas. The above visual shows the mq2 gas sensor module, more details are given below.

Connect The Mq2 Sensor To Arduino According To The Following Schematic.

Connecting the mq2 gas sensor module to the arduino is pretty easy. Here’s the image of our gas sensor and you can see, it. Connect the vcc pin of the sensor to the 5v of the arduino.

When The Output Voltage Is Below That Level, A Green Led Will Be On.

The resistance of the sensor is different depending on the type of the gas. To calibrate the gas sensor you can hold the gas sensor near smoke/gas you want to detect and keep turning the potentiometer until. So, let’s get started with how to design smoke detector with arduino & mq2 sensor.

This Module Is Provided With Male Header Interface And Can Be Easily Interfaced With Arduino/Mega Using Male To Female Type Jumper Wires.

There are lpg cylinders which are used as a fuel source for the gas stove. Adding a simple mq2 gas detecting sensor module to the project makes it a combined smoke + gas detector device. Connect the gnd of the sensor to the gnd of the arduino.

Connect The Analog Pin Of The Sensor To The Analog Pin A0 Of The Arduino.

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. Sensitivity can be adjusted by potentiometer behind it: Mq2 gas sensor tutorial for arduino, esp8266 and esp32.
