Problem with ds18b20 and below -15 celsius


I have a problem with ds18b20 measuring under -15 celsius temps. I have two ds18b20 connected to PHOTON and i am using onewire and dallas libraries to read temps from sensors. Everyting is working fine but when outside temp drops under -15 celsius the ds18b20 returns -127c (disconnected).
Any ideas?

Perhaps this post can shed some light for you:


Thanks for the help. Found that also later yesterday. Now I just figure out how to edit that included library in my project.

Thank You very much. Now everything is working. Thanks for quick help!
