Sensor Gas Mq2 Arduino. MQ2 sensor MQ2 is one of the commonly used gas sensors in MQ sensor series It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material Using a simple voltage divider network concentrations of gas can be.
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 sensitivity according to how accurate you want to detect gas.

Arduino Compatible MQ2 gas sensor has high sensitity to LPG Propane and Hydrogen also could be used to Methane and other combustible steam it is suitable for different application in this Arduino Compatible They are used in gas leakage detecting equipments in family and industry are suitable for detecting of LPG ibutane propane methane alcohol Hydrogen smoke.
Smoke Detection using MQ2 Gas Sensor Arduino …
The Grove Gas Sensor(MQ2) module for Arduino is useful for gas leakage detecting(in home and industry) It can detect LPG ibutane methane alcohol Hydrogen smoke and so on Grove Gas Sensor(MQ2) for Arduino Seeed Studio JavaScript seems to be disabled in your browser.
How to use MQ2 gas sensor with Arduino Step by step
The MQ2 gas sensor has an operating voltage between 45V and 5V that is also used as heater for the surface of the SnO2 Therefore the microcontroller we use has to provide a stable 5V output Arduino microcontroller have already an operation voltage of 5V but we have to power the ESP8266 and ESP32 boards via USB to get an 5V output.
