Ventilation plays an important role in preventing airborne infections. Opening a window helps, but real ventilation is about consistent airflow. COโ‚‚ monitors can give a simple signal of how much shared air is building up indoors.

@njms I love using my #Aranet #CO2Monitor to submit readings to the Indoor CO2 Map! Helps me feel like I'm doing my part in something bigger.

Recommendations for small affordable1 CO2 monitor, that really measures CO2, with sensor such as SCD30, not VOC equivalent. Something that would fit in pocket.

Don't want logging or app connection.

Is there such a thing? What's around these days? ๐Ÿ™

1 E.g. not Aranet, it's big and expensive.

Trump admin tries to kill the most indisputable evidence of human-caused climate change by shuttering observatory

The Mauna Loa laboratory in Hawaii has measured atmospheric carbon dioxide, which โ€” along with other planet-warming pollution โ€” has led directly to climate change, driving sea level rise, supercharging weather and destroying food systems.
