First off I wanna say how awesome it is for this topic to have ignited so much posting and enthusiasm and knowledge of everything that I love, temperature/humidity accuracy. However, so much posting of this vs. that sensor has me so confused. Some people say the 15 is better, some say the 31 is better, some say the 75 is better. I live in North GA in a generally very humid climate in summer, and my 31 has hit 100% once this summer but regularly hits the upper 90s every night, so my guess is that I have a good sensor. However, my main goal is temperature accuracy (always has been, always will be). WRT that, which is better, the 31 or 75? Also, Dendrite has possibly inspired me to remove my filter for more roller coaster readings which I love (to be able to catch all the extremes of the day, no smoothing crap!). I'm still debating it.
