Gravity: Analog Hydrogen Gas Sensor (MQ8) Shipping:2-4 Weeks Starting from basic LED controlThis is an Arduino hydrogen gas sensor. It has high sensitivity to Hydrogen (H2) and less sensitivity to alcohol, LPG, cooking fumes. Hydrogen gas is highly flammable and will burn in air at a very wide range of concentrations The sensitivity is able to be adjusted by the potentiometer. The output is proportional to the density of the gas. You can use analog reading to read the data from this sensor. To ease the difficulty of using this sensor, a
