Matrix MQ2 Gas Sensor FriendlyARM WiKi

The MQ2_Gas_Sensor module mainly consists of a MQ2 gas sensor which is stable and responsive. The sensor uses SnO2 as its gas sensitive material. When its surrounding environment has combustible gases its conductivity change is positively proportional to the gas concentration and this change will be converted to analog output signals. Its sensitivity can be adjusted via the potentiometer.
