Luftqualitätssensor MQ135 Kallibrieren

· 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. Ich wollte damit mal einen StadtGas Sensor bauen. Da der aber nur Vergleicht, habe ich es dann gelassen. Die Konzentration des GasGemisch …
