As the pandemic began, we covered the maker’s civic response in a series of articles and videos that we called Plan C. As we now expect a gradual return to normal activity, approaching an end of the pandemic, we call this new series Plan CO2 — how we might get back together safely. The science […]

Tim Dye of TD Environmental Services is a leading expert in air quality sensors. He knows a thing or two about CO2. When I first started thinking about how we might use CO2 to measure the proper ventilation of indoor spaces, I thought of Tim and his work on air quality monitors.
When I saw the big emoji (old school – smiley) on Carter Nelson’s RGB Matrix Portal Room CO2 Monitor project on Adafruit, I knew he was on to something. I wished that I would begin seeing more such displays in places like restaurants and shops, not to mention school classrooms, offices and makerspaces in the coming months. In Carter’s Adafruit project, the CO2 monitoring device presents a concise public-health message.
