This has been sitting in the draft box for 12 months because the Lexan got destroyed in a storm so I never got to implement the whole system.
A side goal of Gen 2 is to make the electronics a little cleaner and easier to deal with. So I found some really nice perf board at work and cut a small piece to make a shield for the Arduino.

Bottom of the board. Tried to be a clean as possible. Have a great soldering iron really helps, I used the professional Welder at work. Compared to the work, I did last time with my fat tipped one this is amazingly clean.

Top of the board, has connectors for 4 2 pin sensors and a 6 pin header for the relay board.

Last time around I created this crazy sensor stalk. It had all of the sensors going into a 8 pin header I think. It was a mess to solder and dealing with placing the sensors in the system was a pain. This time around each sensor is discrete and has heat shrink and a crimped two pin connector.

The whole system put together with the Open Squid. I used an old 4 pin cd-rom audio cable(is a tad bit too long) for the 4 IO lines and a 2 pin jumper for 5V and Ground.
I will need to add the transistor circuit for the 12V fan. There should be enough to add this to the bottom of the shield.
