Step 1: Connect all of the necessary electronics

This is the easiest step. Since I got the Cana Wireless kit all I had to do was connect the wireless USB wifi and my USB-UART adapter to the Raspberry Pi.

Step 2: Configure the Raspberry Pi

Step 2a: Load the operating system

First you need an HDMI card and a keyboard to do the initial configuration. Connect the Raspberry Pi the TV and your keyboard. To configure the Raspberry I used the 8Gb SD card that came with a pre-loaded version of NOOBS. I selected the option to install Raspbian. This took about 20 minutes to install. Once it was installed I configured it to connect to my wifi. With the Rasberry Pi connected to the wifi I could move it off of the TV and connect to it using putty. You can download putty from here:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

ifconfig

This will show you the Rasberry Pi's IP address. Use this address to log-on to it with putty. My Raspberry Pi's IP address was 192.168.0.40. The putty login screen then looked like this:

And now you're connected. Just a few more steps.

Step 2b: Generate the SSH KEY

Generating the ssh key for the raspberry pi was extremely simple...here's how I did it. If you're starting from scratch you probably don't have an ssh key set up. Here's how you generate one.

ssh-keygen -t rsa -C "Raspberry Pi 0 Key"

This might take a second to generate. Just press enter twice. You can add a password to give yourself extra protection but for this project I'm not to worried if someone takes my pH data so I just skipped it.

Now you need to print out the ssh key:

cat ~/.ssh/id_rsa.pub

I use bitbucket so I just went to my settings and added another SSH Key to my bitbucket account.

Step 2c: Connect to bitbucket and download the repo

Again very simple. Here's how it's done.

mkdir /path/to/your/project 
cd /path/to/your/project
git init 
git remote add origin ssh://git@bitbucket.org:vivaplanet/ras-pherry.git

This will download the files that atlas scientific provided with some modifications I've made. I'll walk through how this code works in a different section but this is all you need to get going.

Step 3: Upload Data to the cloud

Step 3a: Initialize the python code

I recommend running this in the background. This is what the '&' does. Type this command:

python saveFile.py &

python postData.py &

Step 3b: Visit the data portal

go to:
