Leider konnte ich das Modul nicht sinnvoll betreiben. Trotz mehrfacher Versuche war es mir nicht m\u00f6glich, mehr als 0.2 Volt Unterschied am analogen Eingang zu erzeugen. Dies h\u00e4ngt damit zusammen, dass das Mikrofonsignal direkt, ohne Verst\u00e4rkung, auf den analogen Ausgang des Modules gegeben wird. Der Schwellwertschalter funktioniert, ist aber leider nur sehr ungenau einstellbar. Ich habe zwei Module aus Fernost verwendet, evtl. haben diese Fehler oder ein Mikrofon mit falschem Pegel. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ich habe mir 3 andere Module bestellt, unter anderem den KY-037 mit hoher Empfindlichkeit, evtl. bringt dieser bessere Ergebnisse.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"verwandte-beitraege\"><span class=\"ez-toc-section\"
