MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

· These gases can be measured in concentrations between 300ppm and 10,000ppm. Because it takes some time until the surface is hot, the MQ2 gas sensor has a preheat duration of around 2 minutes and has a current consumption of 88mA also during the preheat duration. With a 5V supply voltage, the MQ2 gas sensor has a power consumption of 440mW.

MQ2 Gas Sensor Pinout, Features, Equivalents & Datasheet

· The MQ-2 Gas sensor can detect or measure gasses like LPG, Alcohol, Propane, Hydrogen, CO and even methane. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers.

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 detected.
