I need several sensors to quantify temperature, humidity, air speed, luminosty and maybe even air quality.

I'm hoping you plan to measure luminance rather than luminosity.

You're right, I translated the word directly into English -didn't know what luminosity was, so thanks!

As for the others, thanks for the answers. I'll have a look at digikey.

Any more suggestions?
