I’ve got a problem which drives me crazy
I need to control a refrigerating system able to reach -40°C and I thought that, due to its technical specifications, probe DS18B20 would have been proper for that aim.
I applied the mentioned indicative libraries ( Onewire and Dallas Temp.) and everything runs smoothly untill -15°C.
As the system reaches that thresold, by the way, the probe signs " error".
I’ve been searching for further infos anywhere while finding only one post saying that the problem is due to the Dallas Temp ( seems like about conversion matters) but no solutions are given.
Can Anyone help me? Did anyone experienced such a thing before? I really need to solve this problem urgently as this occurrence is preventing me to supply my customer in due times.
Thanks in advance.
