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 …

MQ2 Smoke Sensor; Arduino board; Buzzer; The MQ2 can be obtained very cheaply, just a few bucks. A good place to look for it is on ebay, which always has auctions on them for the 23 range. Important, it is recommended that you do not obtain the standalone sensor but the whole MQ2 board. This is because if you buy the standalone sensor, you will have to finish building the whole schematic ...
