DS18B20 wrong wiring #9

Closed energiebrand closed 2 years ago

energiebrand commented 2 years ago

Hi Marcus, build your motor-focusser last year and still in operation with Astroberry / INDI on my Newton. We had some discussion about the problem with ASCOM... Now I developed some new 3D parts for a SVBony APO since the buttons on the 1:10 gear are bigger than yours. However first time I added an 18B20 and burned my fingers... the wiring on your diagram is wrong. + and - are inverted.

You are right! I think the DS18B20 part in Fritzing is wrong because it says VDD | DATA | GND:

But data sheet says it's GND | DATA | VDD https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf

The broken Fritzing part might be the reason why I burned my fingers several times on the temperature sensor too :laughing:
