Interfacing MQ2 to ArduinoMQ2 Gas and Smoke Sensor

20160223· Both MQ5 and MQ2 are basically gas sensors but their range of sensing different gas levels vary. For example, MQ5 can sense LPG in a broader range of 200 ppm to 10000 ppm, where as the range of MQ2 for LPG is short and is from 5000 ppm to 10000 ppm. Similarly MQ2 is sensitive to smoke where as MQ5 is not that sensitive to smoke. So we can not choose MQ5 gas sensor to …

MQ5 Gas Sensor Semiconductor Sensor for Flammable Gases

The MQ5 Gas Sensor module is useful for gas leakage detecting. It can detect LPG, ibutane, methane, alcohol, Hydrogen, smoke and so on. MQ2 can sense methane(CH4) upto 20000 ppm where as MQ5 can sense CH4 only upto 10000 ppm. The difference between MQ5 and MQ2 therefore lies in its range of values. Specifications:Indication of the signal output.
