Interfacing MQ2 to Arduino- Gas Sensor for Smoke-Butane ...

· · 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 …
