In order to connect up 5 DS18B20 temp probes and make sure all the wires and connectors work correctly 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:
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.
Next trick was to get 5 connections completed.
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.
