CO2Sensor gegen Corona: Version mit ESP8266, MHZ19B und Tasmota. Wie das Umweltbundesamt in dieser Stellungnahme am 12. August 2020 schreibt, wird das CoronaInfektionsrisiko in Innenräumen durch Lüften stark verringert. Ein guter Indikator für ausreichenden Luftwechsel stellt die CO2Konzentration dar, die unter 1000 ppm bleiben sollte.

MHZ19 should disable ABC mode (Auto Base Calibration ...

· The MHZ19 sensor has ABC enabled from factory, or at least two of my sensors now have their baseline messed up because the ABC mode was not disabled. The automatic base calibration will set the lowest measured internal RAW value in the last 24h as new reference point at 400 ppm. This means the base line will make a big jump when being used in a not well ventilated room for more than …

Unsinnsbasis

· Bei der Programmierung des CO2Sensors MHZ19B war aufgefallen, dass dessen Temperaturmessungen im Vergleich mehrere Grad über denen anderer Sensoren lagen. Auch die zum Vergleich genutzten Sensoren lieferten Werte, die tlw. um mehr als 1°C voneinander abwichen. Also schien ein Vergleich der Umweltsensoren mit Temperaturmessung sinnvoll. Neben sechs Exemplaren …

· MHZ19 CO2 Reset the basic value. I have isolated sensors, whose basic value of about 400 ppm was not correct. This is most noticeable when comparing the displayed values with their other sensors. Fortunately, the value can easily be reset. It is important that the real value also corresponds to the basic value in the atmosphere. This can be easily checked with another sensor. I then simply ...
