I'm using a DS18B20 temp probe that I ordered from a shop in china. The first time the accuracy was good enough. But after some months it's getting more and more worse. Some reads have a inaccuracy from more than one degree now. Absolutly inacceptable.
Can you suggest any Water proof reliable temperature probe that is compatible with the raspberry pi without a Arduino and without making a custom circuit by myself (for an analog probe) Or a shop / manufacturer where I can buy areliable DS18B20?
