MQ7 carbon monoxide sensor
Posted: Fri Apr 06, 2018 11:44 am
Dear All,
I wonder if any of you have used the MQ7 sensor? I have a few of Flying Fish modules from China. I read on an Arduino forum that some kind of modifications on board are needed to make it work. I don't need a 1ppm accuracy, just simple "CO is present more than it is usual". Any sample code would be greatly appreciated.
