Apr 30, 2020· Ich habe eine zweite Variante getestet. Aus dem Internet habe ich einen einfachen Sketch für den CO2Sensor gefunden: Als Ausgabe auf dem seriellen Monitor bekomme ich nur diese Fehlermeldung: Ich habe den MHZ19b so verkabelt: Tx > A0 Rxd > A1 V+ > 5V V > Gnd PWM > Pin9. Ich freue mich, wenn mir da jemand weiterhelfen kann.

Dec 27, 2020· MHZ19D: to Volts DC Have watch out for the MHZ19C (and MZZ19D). Getting a supply of between volts and volts (a very narrow range) from a USB port can be "delicate" And if you don''t have a multimeter to measure that the voltage that reaches the MHZ19C is within these ranges, I recommend avoiding it.
