Just what I posted before. Next time I have a nice clear day I'll take more pictures of a properly installed sensor assembly against the blue sky (it doesn't show up well against my white photo backdrop) for the website.
Just about got the dew point calculation done. I may make another attempt to actual calculate it on the fly, but I realized the other day that I've got tons of external flash memory and I can just build a lookup table for dew point and wind chill and save some processor time and code space.
