Technik & mehr von damals und heute
This project – actually a mini project – might also be interesting for one or the other. It is the now well-known and frequently used carbon dioxide sensor SCD30 (CO2 sensor) from the manufacturer Sensirion. There are a number of projects that can be found on the internet.
