Nr. 51 CO2 Messung mit Arduino "CO2 Ampel" | Funduino ...

In Schulen wurde in Zusammenhang mit der Covid-19 Pandemie der Ruf nach sogenannten CO2-Ampeln laut. Diese Geräte messen den Co2 Anteil in der Umgebungsluft und visualisieren die Messwerte mit Hilfe einer Ampel. Sobald bedenkliche Mengen CO2 in der Raumluft vorhanden sind, wechselt die Ampel von einem grünen Licht schrittweise über ein gelbes Licht zu einem roten Licht. Dadurch wird ...

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· Instead of calibrating at 0ppm CO2 (nitrogen), the sensor is calibrated at 400ppm CO 2 (outdoor air is actually very close to 400ppm), then 400 ppm is subtracted from the newly calculated offset value. Fresh air calibration is best for sensors in manufacturing settings or greenhouses where the sensor is constantly exposed to different CO 2 levels.
