    did not get either of these to work
    bought one of these a few years ago and it is still functioning. Neither of these worked using their analog outputs nor with their digital outputs using test Arduino code with +5V, Gnd and reading on either A0 (analog) or D2 (digital). All i get is a nearly constant low reading irrespective on any sounds made (analog). Tried changing the pot used for digital but no effect either.

      1.0 out of 5 stars Schrott ....
      Reviewed in Germany on 25 June 2019
      Verified Purchase
      Ich habe diesen Sensor leider bestellt, da er ganz oben angezeigt wurde. Es gab auch noch keine Bewertungen dazu. Der Sensor kann über einen Poti eingestellt werden. Hat man das Glück und findet einen sweet spot, so scheint dieser nach ein paar Minuten Betrieb wieder verloren zu gehen. Dann erkennt der Sensor entweder alles als Geräusch oder nichts. Artikel wird zurückgeschickt ....

      Funziona perfettamente, rileva il parlato, a voce leggermente alta, anche a un paio di metri di distanza. Bisogna solo avere un pò di pazienza nel tararlo. In precedenza avevo provato un altro modello ma quello per davvero era poco sensibile.
      Utilizzo l'uscita digitale, quella analogica non l'ho neppure considerata ma credo sia equivalente.

      Il sensore è arrivato non funzionante. Come si vede dalla foto entrambi i led rimangono sempre accesi nonostante agisca all'infinito sulla vita di regolazione! Non vorrei fare il reso per evitare inutili giri vista la spesa ridotta..ma almeno uno sconto sull'acquisto di un altro sensore identico. Grazie.
