Same. I read through this thinking "What, my team sensor on the data logger for my coffee grinder might be more than half a degree out? You know what? I totally don't care, and wouldn't have spent an extra 50 cents to get that much accuracy..."

I do have ethical qualms about supporting/funding "stolen IP", but then I've kinda got ethical qualms about the whole concept of IP anyway, and if you wanted to go hardline on IP compliance you'd probably have to avoid everything out of China (and everything that contains components out of China)... I wonder how often Apple get counterfeit components slipping through on Foxconn production lines, and how much effort they put into stopping it beyond extensive QA - which only ensures any counterfeits that make it through need to be close-enough to functionally equivalent to pass all the tests? The "test after" approach kinda pushes towards more IP infringement rather than less, since it's likely parts built from stolen designs would pass more often that parts reimplemented according to the spec?

If you don't need that accuracy, why would you use a DS18B20 in the first place. You can use a dirt cheap NTC.

Maybe you want to save on the A/D hardware?
