MQ-2 Sensor und Luftqualitäts-Sensor – ein Vergleich ...

· Neulich habe ich Euch einige Gas-Sensoren vorgestellt, welche Methan, LPG usw. messen (-> siehe Blog-Beitrag). Der Test hier zeigt einen Vergleich zwischen dem Luftqualitäts-Sensor, welcher leider nicht mehr erhältlich ist, und dem MQ-2 in dem selben Raum und dicht nebeneinander gestellt. Einige Meßwerte gingen schief, das lag aber darin, das Zug im Raum war und der MQ-2 falsche …

Carbon Monoxide Gas Sensor MQ-7 - Arduino Project Hub

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
