The MQ-9 Gas sensor can detect gases like Liquefied Petroleum Gas (LPG), Carbon Monoxide (CO) and Methane (CH4). Similar to other MQ series gas sensor, this sensor also has a digital and analog output pin. When the level of these gases go beyond a threshold limit in the air the digital pin goes high. This threshold value can be set by using the on board potentiometer.  The analog output pin, outputs an analog voltage which can be used to approximate the level of these gases in the atmosphere.Â
