Hello , I want to know, how you determine Ro in your library? thanks

yanoschik commented 8 years ago

Just read the code and you'll find calibration at startup... (btw. I got this lib slightly updated MQ2Lib)

labay11 commented 8 years ago

It's done in the begin() method in MQ2.cpp which assigns the value returned by MQCalibration()

And thank's to @yanoschik for updating this library.
