I am considering adding Ethernet capability

By adding Ethernet capability I can write the data I am currently collecting on the micro SD card to a browser directly. This means I could pull up Firefox and go to my Arduino’s IP Address and see the data.  This will give me the ability to read the data from anywhere on my home network as well as anywhere I can get internet connectivity, potentially allowing me to review data from a smart phone remotely. Additionally I could control relays from a remote location as well. But for now the ability to ease the data collection and monitor the process remotely will be a great first step. First I have to buy an Ethernet shield.  For those of you not familiar with Arduino this means an additional plug-in board that will stack on top of the Arduino pins.

Here’s a picture of just the Ethernet shield, the connection point you see on the front is the plug-in point for the Ethernet connection. This is a RJ-45 connector. I was able to get a 100 foot Cat 5 with installed RJ-45 connectors for $27 at Home Depot.

At present I have already have a prototype shield plugged into my Arduino Uno. This allows me to easily disconnect and update the Uno without disturbing any wiring connections. There are quite a few wiring connections for the RTC or Real Time Clock, the LCD display, the outside temperature thermister, the boiler water tank thermister, the Auger Feed pipe thermister as well as Relays to turn on the Auger motor and boiler tank water circulator. But when I attempted to plug in a prototype shield into the Ethernet shield there was interference with the RJ-45 connection point. The prototype shield would have grounded itself on the metal so I have ordered Stacking headers to extend the height above the shield. More when the headers arrive.
