what would be the easiest approach for this?
I have 3 different "sensor packs", each of which have ex. humidity, barometer, other (~3-4).
What would be easiest way to implement this kind of modules?
I was thinking of going with Arduino Uno for prototyping, but all other OK too.
In the end I'd prefer to use ATTiny though, so using same amount of I/Os should be important (?)
