Hi everyone,

I'm getting ready to setup my first one-wire network that's larger
than my work bench. I've read some of Maxim's notes, in particular
https://www.maximintegrated.com/en/app-notes/index.mvp/id/148, and
wonder whether there's any other gotchas to look out for. You're all
such nice folks, I'm sure you'll let me know if there are any... :)

The network will be about 30ft in length with two 6ft stubs coming off
in the middle. Four DS18S20 temperature sensors will be attached. One
sensor will be near the master and the rest at the far end and the
stubs.The master is a Raspberry Pi.

Three conductor, shielded cable will be used for the network. Based on
my reading, this isn't such a large network, but the gotchas worry me
(that and I only want to rig this up in the house crawl space once.)
Due to the length, noise and reliability are my concerns.

1) Raspberry Pi I/O isn't 5V tolerant, so the bus pull-up is to 3.3V
Would there be an advantage to powering the sensors at 5 instead of
3.3 volts?

2) Would bypass caps be advisable at each sensor?

3) Is there anything else I should consider? :)

Thanks for any help. I really appreciate what I learn from this list.

Take care.
