為求連接5 DS18B20溫度探針並確定所有線路的正確連接took some effort.  The fact that a pull-up resistor is required to take readings was an issue for me.  I have been using 1/4 watt resistors and in tight spaces my resistor wires kept breaking off.  So I needed a way to connect it all up and be protected.  Sugru saved the day.

I showed you the end product as that is what most people are interested in.  But it is important to understand how the end product was created.

Here is the starting point:


pull-up resistor configuration

Spacing of the wires and
resistor is a big issue here, as if the spacing is off the connectors will not
fit into the holders correctly.


one connection made

Next trick was to get 5
connections completed.


5 connections made


bend it just right to get correct spacing

end product

Now it is possible to continue testing my
DS18B20 temp probes with more than 2 probes.  This creation will allow me
to build a temp probe hub using Cat 5 cable and RJ45 connectors.  This
harness will also make it possible to stay with my basic premise of being able
to replace any component in my systems with in 5 minutes.
