Airvalent CO2 monitors. https://airvalent.com/ Exciting to see how small these are getting, similar size to apple airpods case. Looking forward to seeing this tech ~1-3 versions from now, where air quality monitoring can just be part of a smartwatch.

Pretty sweet. Substantially smaller than ones I have. Also, highly recommend everyone have a co² monitor that shows a numerical value, especially if you have any fossil fuel use in your house for heating/cooking/etc.
