For medical reasons, I'm interested in measuring the following, with the ability to capture the data and plot it over time from the air that you exhale / breathe out:
- hydrogen sulfide
- nitric oxide
I would be tempted to also say that heart rate would be nice at this point as well, but that can be pulled from other devices that somewhat do it better (eg. fitbit - though it'd be nice to plot the data against one another..)
I don't know what sensors I'd use for this or where to start looking?
