Atlas Scientific makes an amazing suite of scientific grade environmental monitoring sensors that have a perfect synergy with the Plotly data visualization platform.

This Instructable will show you how to hook up an Atlas Dissolved Oxygen sensor and a Raspberry Pi to Plotly's real-time graphing platform. You will view your data in real-time in your web-browser! Here is our final product: A graph of our dissolved oxygen sensor in our Montréal office: http://plot.ly/~streaming-demos/52/!



You can also use Atlas's pH, ORP, and EC sensors simply by swapping out the appropriate circuit and probe. Calibration functions will vary for each sensor. This will work with the Arduino Yun, Beaglebone Black, or any other embedded linux platform.
