MQ Gas Sensor with Arduino

MQ Gas Sensor use a small heater inside with an electro-chemical sensor. They are sensitive to Gases.Whenever the concentration of gas increases the resistance will decrease (but the current flow will get increased). It leads to change in voltage and it is read at Analog out pin which tells how much gas is concentrated in normal Air. This varied analog...
