Not trying to be rude, but yes carbon dioxide, not carbon monoxide, and
where can I buy a sensor?

As a veteran confined to my home, I have time to think and act only in my
small corner of the world. Since I am in my home almost 24 hours a day, 7
days a week, I would like to maximize the health I have. I exercise and
get
fresh air outside my back door, but as it gets cold, I spend much more
time
inside. So the subject line is my question and how do I monitor it.

For a few years I worked part time for a medical oxygen supplier. I did
tests on equipment used in people's homes, mostly for oxygen. I never found
a difference in carbon dioxide by more than a half percent or so. Relax and
enjoy your life.
