Clouds meter <> establish the height of clouds through an IR measurement temperature of saturation.

Like a real pyranometer, realize a measurement of sun power.

I have started to build it for a homemade amplifier, to set the speed of the fans by the temp of the heathsink and so on.

If you can't fix it in software you'll have to fix it in hardware in this case. Hence the NMEAtor.

Aviation meteorology station with Arduino.
