CO2Sensor MHZ19B Unsinnsbasis

+

10/11/2020· Der MHZ19B ist ein CO2Sensor, mit dem man eine CO2Ampel selbst realisieren kann. Durch die CoronaPandemie (COVID19) sind zur Messung der Luftqualität in Räumen, die von mehreren Personen gleichzeitig benutzt werden, vermehrt CO2Sensoren im Einsatz ( in Klassenräumen in Schulen). Der CO2Wert gibt einen Hinweis darauf, wie „verbraucht” die Luft ist indirekt wird daraus …
