Introduction: Open Source Server Room Monitor
This server room environmental monitoring system is a low cost high performance device with the same onboard features as commercial devices costing hundreds of dollars more. In addition to a low cost platform we will provide low cost sensors for many important devices to insure your equipment stays safe and sound.
Full instructions are available at sproutboard.com as well as several kits to create some very unique projects.
Step 1: Stuff You Will Need...
You will need a few parts for this build as follows:
Sprout Board: sproutboard.com
Arduino Duemilanove: Trossen Robotics
Ethernet shield: Sparkfun.com
Rack Mount Chassis: sproutboard.com
LCD Screen: Sparkfun.com
Audio Board: Sparkfun.com
Temperature / Humidity Board: sproutboard.com
Power Supply: Sparkfun.com
Odds and ends, screws, glue, tools, etc...
Step 2: Putting It Togeather
The assembly of the sprout board is very simple and requires very little experience with soldering. There are a few places where adding components can get cramped, but if you take your time it will be very easy.
Mount your arduino, ethernet shield and lcd screen
Glue the chassis togeather
Mount the board on the chassis
Step 3: Add Accessories
Next plug in any sensors you want to. I am using a temp/humidity and sound sensors.
Step 4: Load Software and Do a Happy Dance!
So all we need to do is load our software and do a Happy Dance!
Use this link so anyone can download the pde that will test the system. This also is an excellent framework to customize your application.

CWe have provided 6 headers that can be used for expanding the capabilities of the sprout board to add additional sensors, input devices or control external devices. On the left side we have 2 analog terminals and on the right we have 4 Digital terminals. These terminals all have a set of three sockets that all use the same configuration of 5V+ on the left, I/O in the center and Ground on the right. In addition the two analog ports can simply be configured as digital I/O as needed with the arduino pinmode.
We have added these jumpers to our board to allow for very flexible connection of additional circuits through the accessory terminals. This configuration allows for you to setup a 2 wire button for input, have the option of both 5v and GND on an external device, or even ground your floating analog pins for more constant signals.
We have added a serial header on this board to allow you to connect a LCD screen with ease. As you can see in the picture here we have our 3 terminal block mounted at the end of the board. From left to right we have 5V+, TX, Ground. If you choose to use a spark fun Serial LCD display this allows for the simplest and most user friendly addition you could ever want.
