Die drahtlos angesteuerte Rufanlage dient zum Absetzen eines Notrufs, welche speziell für Menschen mit Einschränkungen der oberen Gliedmaßen entwickelt wurde. Anstatt wie bei herkömmlichen Rufanlagen, wo eine Taste gedrückt werden muss, um den Alarm auszulösen, erfolgt bei dieser Rufanlage die Alarmauslösung über Messung der Temperatur. Die Rufanlage ist in der Lage durch Messung der Temperatur zu erkennen, ob der Sensor zwischen die Lippen genommen wurde oder nicht, um so einen Alarm auszulösen. Der Alarm wird am Basisgerät, an welchem der Temperatursensor angeschlossen ist und am mobilen Empfangsgerät ausgelöst.
Die Alarmauslösung auf beiden Geräten erfolgt innerhalb von 500 ms ab dem Berühren des Sensors durch die Lippen und die Reichweite der Funkverbindung beträgt mindestens 100 m im Freien. Beide Geräte können mit einem Li-Ionen-Akku der Größe 18650 mit 3,7 V versorgt werden.
Die Rufanlage wurde so entwickelt dass diese möglichst Kostengünstig und einfach nachzubauen ist.

Questions
How big is the Callsystem PCB?
It measures 95 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Callsystem use?
59 parts, built around the MT3608, DW01A-G, AO3401A and FS8205. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Callsystem KiCad files?
From the thomas1299/Wireless-call-system repository on GitHub, at the commit this page was made from: the board is PCB_Board/Callsystem.kicad_pcb and its schematic PCB_Board/Callsystem.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Callsystem design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
