Hooking up a gas smoke (MQ2) sensor Sensors Arduino ...

May 06, 2021· The heater should warm the sensor, after 5 or 10 minutes the metal of the sensor should get warm. The ''signal path'' is like this: 5V to both ''A'' pins > ''A'' to ''B'' is the sensor > both ''B'' pins to resistor and to analog input > resistor to ground. Also, 22k is very high. The output could be at the maximum. I would suggest to use 2k2 to start ...


Smoke Detection using MQ2 Gas Sensor Arduino Project Hub

May 06, 2016· The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: 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.

MQ2 Reading different gases Sensors Arduino Forum

May 06, 2021· MQ2 Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.


MQ2 Gas Sensor Working Principle Its Applications

Aug 12, 2019· MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas.
