Stemma QT + Matrix Portal CO2 monitor
This is an easy-to-read CO2 monitor that uses the SCD-30 NDIR CO2 sensor connected up to a Matrix Portal + 64x32 Matrix. It's super visible and gives visual hints so you know when its time to crack open the window, or when you're in good shape. We're seeing a lot of students+teachers want to build something like this for their classrooms so this version could be helpful - its totally plug and play thanks to Stemma QT! https://learn.adafruit.com/matrix-portal-room-co2-monitor #adafruit #c02 #airquality Visit the Adafruit shop online - http://www.adafruit.com…
