Ground connectors completed and tested

I am getting closer to getting 20 probes ready to test.  Everything is just about in place to make a run at it.  So stay tuned we are getting close now…….

Hello there,

I am in the same boat trying to set up some onewire multiple ds18b20 sensors over a 100m mixed topology network.

Could you please post some information regarding the length of the wires? Is it a star topology? Bus? mixed?

Giannis – Thanks for the feed back on my blog efforts. It is good to know see value in my efforts. As to your questions on the probes. I have only run about 10 to 12 feet so far. I have read that others have run 75 to 100 feet with no problems. But as always on the internet fact and fiction run close together on these type questions. I have not done it, so I do not know for sure. All the connections I do and have done are all bus type. I really do not yet understand star topology to the fullest. It used to drive me crazy when computer networks were configured this way.
