MH-Z19 & MH-Z19B

Auto Calibration: The MH-Z19 is a sensor that is designed to be powered on and rarely turned off. The sensor calibrates over time (if autocalibration is on) using the lowest CO2 observed in the prior 24 hours). After 3 weeks, a value is stored with an accuracy rating, this can be requested using getAccuracy(). ABC must be disabled each day, however this is handled by the library.

06/05/2021· Die Werte sind etwas anders, aber Gelesen ist trotzdem Null. Beim zweiten Sensor scheint ein Wackelkontakt vorzuliegen, weil die Ausgaben auf dem seriellen Monitor nicht regelmäßig erscheinen. Bevorzugt dann, wenn ich das PWM Kabel bewege.
