Bewegung

Als Bewegungssensor kommen zwei Sensoren in Frage; aufgrund der verschiedenen Techniken der Bewegungsermittlung mit entsprechenden Vor-/ Nachteilen:

Modell Technik Kosten Fakten Bild
AM312 PIR IR ca. 0,80 € - 0,90 €
  • klein
  • günstig
  • nur ein PIN benötigt
  • Abdeckung/ Kuppel muss außerhalb des Gehäuses in Abdeckungsrichtung sein
  • Abdeckung:
    • ca. 100 °
    • ca. 3-5 m
AM312.png
RCWL-0516 Microwave ca. 0,25 € - 0,50 €
  • klein
  • noch günstig
  • nur ein PIN benötigt
  • kann unter Umständen durch Hindernisse erkennen (wie z.B. ein verbautes Gehäuse aber ggf. auch Wände)
  • kann daher versteckt im Gehäuse platziert werden
  • Abdeckung:
    • 360 °
    • ca. 5-7 m
