I need to measure efficiency of of solar panels during various conditions such as amount of uv (full sun, shade, night, night with full moon) and various temperatures. I know there's a DataLogging Python script which can probably help with the data capture, but can anyone advise on hardware I'd need and how to interface it with a Pi?
I found this and they have many other options but can I just plug this straight into a GPIO port or should there be some other shield or ardiuno in the mix? Do I run it in a voltmeter board and are these just display only or pass can data be captured? Perhaps that's already an option on a base Pi?
