          <div>Hallo, <br>
            <br>
          </div>
          ich kann nun einen Erfolg verkünden. Bevor ich die Schaltung
          um etliche Widerstände und Kondensatoren erweitert habe,
          wollte ich zumindest einen Versuch unternehmen, den 4,7 kOhm
          Widerstand gegen einen 1,1 kOhm Widerstand auszutauschen. Die
          Schaltung funktioniert ohne Probleme. Alle 19 angeschlossenen
          Sensoren werden fehlerfrei ausgelesen. Jetzt bleibt nur noch
          die Frage, wo ich den einen noch übrigen Sensor sinnvoll
          einsetze. :-) <br>
          <br>
        </div>
        <div>Vielen Dank für Eure Unterstützung. <br>
          <br>

                                          <div>Hallo, <br>
                                            <br>
                                          </div>
                                          danke für Eure Hinweise. <br>
                                        </div>
                                        Ich fasse kurz zusammen. <br>
                                      </div>
                                      Jan hatte geschrieben, dass er 16
                                      Sensoren mit einem 1,1 kOhm
                                      Widerstand betreibt. Auch Matthias
                                      hatte gestern die Idee geäußert,
                                      den 4,7 kOhm Widerstand gegen
                                      einen kleineren zu tauschen. <br>
                                      <br>
                                    </div>
                                    Der Vorschlag von Udo geht nun noch
                                    etwas weiter. Vor jedem Sensor einen
                                    4,7 kOhm Widerstand zwischen 5V und
                                    Data, einen Kondensator zwischen 5V
                                    und GND und einen 100 Ohm Widerstand
                                    in der Data-Leitung. Bei geplanten
                                    20 Sensoren würde dies die Schaltung
                                    ziemlich verkomplizieren. <br>
                                    <br>
                                  </div>
                                  <div>Was meint Ihr? Erstmal probieren
                                    ob es mit einem kleineren Widerstand
                                    funktioniert? <br>
