The beauty of 1Wire is that ALL sensors share lines. Theoretically as
many 1Wire devices as you want can be daisy chained, as they all have
unique IDs. Three wires only required: Data, 5V, GND.
Pinout on 8P8C:
2 +5V DC Power
3 Ground (Green/White)
4 1-Wire Data (Blue)
I have a couple of these pictures around the shop, seem COM1:

With the Ethernet splitter are the voltage sensor and temperature

I have two RaspberryPi with two small 1wire networks but actually know
very little about how this stuff works. I use owfs and python and just
grab current readings from the fuse directory.
Thank you,

If you want to get fancy and enclose it, anything with terminals
will work. Here's one I made recently for outdoors use:

Otherwise, any stupid splitter is fine:

I want to add a temperature sensor, connected by 150 feet of Cat 5.
I presume I should buy a hub to make life easy.
This 1wire network will never have more than three sensors.
Any hub suggestions?
Thank you,
Peter
