#MakeItWithSensirion: Tutorial how to make a CO2 traffic light with the SCD30 CO2 sensor
Photo by Guido Burger
This is #MakeItWithSensirion at its best! Guido Burger and Klaus Uwe-Gollmer, from the German Maker Community, have written an article on how to build a CO2 traffic light to measure the CO2 concentration in classrooms and to find out when it is time to ventilate. They used our SCD30 sensor in Seeeds Studio "SCD30 Grove" module.
The article was published in the German "Make". Click here for the tutorial: https://www.heise.de/select/make/2020/5/2022015381334973804 (German only).
