MQ2 Gas sensor works on 5V DC and draws around 800mW. It can detect LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations anywhere from 200 to 10000ppm. Subsequently, question is, what is MQ in MQ sensor? MQ sensors are special sensors. designed to have sensitivity for to detect some gas like LPG, CO, Propane etc. In Chinese, ''sensitive'' means ''Mĭngăn'' …

LEL (Lower Explosive Limit) LEL, short for Lower Explosive Limit, is defined as the lowest concentration (by percentage) of a gas or vapor in air that is capable of producing a flash of fire in presence of an ignition source (arc, flame, heat). Also question is, how does the mq2 gas sensor work? MQ2 is a metal oxide semiconductor type gas sensor.

20150629· The datasheet also says that it''s internally regulated and will current limit at 155C. Assuming 25C ambient, this only leaves a margin of ~ that can be dropped over the regulator. So you''d have problems with any more than around 400mA. To have a safety margin, I wouldn''t plan on more than 300mA or so, or maybe even down more towards 200. This voltage regulator is a nice, low …
