Overall the low cost developed microcontroller (arduino uno)-MQ2 gas sensor was functioning within the specifications of the sensors sensitivity. Preliminary testing showed no inference for determined Rs/Ro of gases on studied site, implicating acceptable air quality. The design however needs improvement and calibration for convenient application sampling on the study site.
· MQ2 - Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values - from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.
· The MQ-2 Gas sensor can detect or measure gasses like LPG, Alcohol, Propane, Hydrogen, CO and even methane. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas.
