MQ-9 gas sensor has high sensitivity to Carbon Monoxide, Methane and LPG.The MQ-9 gas sensors are used in gas detecting equipment for carbon monoxide, methane and LPG in home, industry or car. The module gives out the concentration of the gases as a analog voltage equivalent to the concentration of the gases. The module also has a on-board comparator for comparing against a adjustable preset value and giving out a digital high or low.
