Customer reviews for "MH-Z19B - CO2 Sensor"
By: Am: 19 Nov 2022

Ausgezeichneter CO2-Sensor mit Kalibrierungsmöglichkeit - Temperaturwerte sollte man nicht verwenden

Die CO2-Messwerte des MH-Z19B sind sehr plausibel. Besonders gut finde ich die Kalibrierungsmöglichkeiten dieses CO2-Sensors. Diese ermöglicht im seriellen Betrieb bei Ausschlatung der Auto-Kalibrierungsfunktion vergleichende Messungen in verschiedenen Räumen oder zu verschiednene Zeiten. Nutzt man den Sensor im Auto-Kalibrierungsmodus, lassen sich nur relative CO2-Änderungen im Rahmen einer Messreihe feststellen. Die Temperaturwerte sind (verglichen mit dem BME280), deutlich zu hoch und möglicherweise durch die bei der CO2-Messung entstehende Wärmeentwicklung beeinflusst. Man sollte über den MH-Z19B also ausschließlich den CO2-Wert messen.
