Just got the Air quality sensor v1.3 and experimenting with it and aruino uno.
It seems to work, the output is everytime around 350 (High pollution!) for a few hours now.
How can I test it and let change this measurements?
I am inside my flat, there is now difference if the window is open or not (in a small town, almost no traffic etc. around)
Thanks for help.
