CO2 Monitors for Indoor AQ Monitoring and Management during the COVID-19 Pandemic

The pandemic has made us aware of the indoor air quality. We have learned that it is important to monitor the carbon dioxide (CO2) concentration inside a room for two reasons: To keep productivity up and to reduce the chances of infection especially, when a room is occupied by many people like in classrooms, offices, etc.

A CO2 monitor can help us estimate the risk of infection of the coronavirus as a high concentration number (above 900 ppm) can indicate that too many people are inside a room, and the air hasn’t been renewed as frequently as the regulations indicate, in some countries.

There are a lot of indoor CO2 monitors in the market, I have reviewed many of them, but I thought it is useful to gather them all together in one place and make your life easier.

Airthings Wave Plus

Airthings Wave Plus features a very low power Senseair CO2 sensors. Additionally, it has a Radon sensor, a VOC sensor, and a temperature/humidity/atmospheric pressure sensor. It can operate up to 6 months with just two AA batteries, and it communicates with your smartphone via Bluetooth. Recently, the company has released a QR code based cards that anyone can scan and see the AQ for a particular monitor.
