Der Aussensensor übermittelt die daten über funk, mittels 433 Mhz,
Jeweils alle ca. 5 minuten, 3 gleiche Sequenzen.
an einer wetter basis können maximal 3 Aussensensoren erkannt werden.

Protokoll Analyse:

Aufbau Aussensensor Aufgeschraubt, Entfernung funk modul, Sende signal "Aufnahme"/Dekodierung mittels PC mit Seriellem port und Lirc Software.
Aufzeichnung mit mode2 binary, umleitung in eine datei.
