CO2 meten met de MH-Z19 -

10-02-2017· Ik heb de MH-Z19 sensor op mijn Arduino Mega aangesloten die het hart van mijn home automation systeem vormt. Het fijne van de Arduino Mega is dat hij over 3 extra hardware seriële poorten beschikt. Zo kan ik de CO2 sensor op maximale snelheid met de Arduino laten communiceren zonder dat dit van invloed is op de rest van mijn programma.
