Sensor Gas Mq2 Arduino

Sensor Gas Mq2 Arduino. This sensor also works in the same way as the MQ3 sensor Also this MQ2 sensor can measure the amount of LP gas smoke carbon monoxide and methane in the air This tutorial explains how to make an LP Gas Measurement Project with Arduino step by step We can buy this sensor in the market at a very low price.

The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases LPG Butane Propane Methane Alcohol Hydrogen The resistance of the sensor is different depending on the type of the gas The smoke sensor has a builtin potentiometer that allows you to adjust the sensor digital output (D0) threshold.

MQ2 Gas Sensor Science and Measurement Arduino Forum

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 MQ2 gas sensor (FC22) powered and interfaced with Arduino Uno.

How to calibrate an MQ2 gas sensor Arduino tutorial

The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases including alcohol carbon monoxide hydrogen isobutene liquefied petroleum gas methane propane and smoke This module is provided with male header interface and can be easily interfaced with Arduino/Mega using male to female type jumper wires.
