Luftqualitätssensor MQ-135 Kallibrieren

· Nun kommt der Sensor nach 24 Stunden auf 500ppm CO2-Anteil. Diese "500" sind Deine Referenz. Weicht der Wert ab (473/523) dann sagst Du dem Arduino "mach was". Es wird also nur verglichen. Willst Du richtig messen, dann brauchst Du eine richtige Referenz. Du brauchst also einen Raum, in dem Du verschiedene Werte simulieren kannst.
