Hi all,
I have a DS18b20 with a 1m (39 inches) cable. I’d love to be able to extend it so I have 2 questions :
- what’s the max length of cable I can get away with?
- what’s the best cable to use?
Thanks in advance!

Hi,
From memory, I think the 1-wire bus is OK out to at least 10 metres. The data rate is very slow (approx 18kbits per second), therefore there is no need for special cables.

Excellent, thanks for the information, I’ll give it a go.
