Nov 10, 2020· Der MH-Z19B ist ein CO2-Sensor, mit dem man eine CO2-Ampel selbst realisieren kann. Durch die Corona-Pandemie (COVID-19) sind zur Messung der Luftqualität in Räumen, die von mehreren Personen gleichzeitig benutzt werden, vermehrt CO2-Sensoren im Einsatz ( in Klassenräumen in Schulen). Der CO2-Wert gibt einen Hinweis darauf, wie „verbraucht” die Luft ist - indirekt wird daraus …
The MH-Z19B carbon dioxide gas sensor (hereinafter referred to as a sensor) is an intelligent all-purpose small sensor that uses the NDIR principle (non-dispersive infrared) to detect the presence of CO2 in the air with good selectivity and anaerobic properties of gas …
