DS18B2O - Temperature probe with RJ45 connector

This Instructable uses the work done by Jonathan Oxer and Hugh Blemings in the book  "Practical Arduino"  at:  
http://www.practicalarduino.com/  

and builds upon the work done by:
http://www.cheapvegetablegardener.com/  

using the homemade-waterproof digital thermometer design concept:

I needed a Stainless Steel DS18B20 (1-wire) probe that could be used in my aquaponics units that I build.  I have to use Stainless Steel as any other metals would have impact on fish health I use in my systems.  Using other designs and materials would work the same way.  I could not find any Stainless Steel DS18B20 probes when I first started this project, so I build my own at first.  Now I have found a source for these so I no longer need to build them.  This saves a lot of time and effort.  Now I can focus on plug-n-play assemblies  that are easy to incorporate into arduinos sketches and control units.
