Quantified Self: CMS50 Oximeter
Posted on February 16th, 2010 by miron

I bought the Contec CMS50-F oximeter from here.
The software that comes with the CMS50 could be more reliable and user-friendly, and only runs on Windows. I ended up spending a day reverse engineering the USB protocol and writing a Python program to acquire and graph the data. The software is on Gitorious.
Here are some of the charts you can get:
