mkay. now, don't feel offended, i'm just poking youwith creative criticism here
reformat everything. use a nice theme. people who make themese are aesthetically inclined and care about readability. you used at least three colors for text, that did not represent separate entites.
use high-res and clean pictures. i can barely read the text on 1600 resolution.
post an explicit schematic of everthing. there is one for the sensor, but i don't think it suffices.
i haven't checked the whole thing, hard to read material is annoying. there's one thing i don't like about it, the fact that you offer code, but little explanation on how it works. maybe you should delimit the code and use a fixed width font, too.
