2021-05-06· 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.
2019-11-20· MQ2 is a sensor module that can be used to detect flammable fumes or gases at concentrations between 200 ppm – 10,000 ppm. What is ppm? ppm stands for “part per million”, which is a unit that states the amount or concentration of substances in every 1 million. Almost the same as the unit of percent (%) which means “per cent”.

2016-02-23· 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. We choose the right sensor based on the application requirement; say for example – We can not choose MQ2 for sensing low levels of LPG in the range of 700 ppm because MQ2 is insensitive low levels of LPG (its …
