Customer reviews for "Humidity sensor - analog and digital"
25 Nov 2022

Tolles Produkt, Anfang war etwas kniffelig

Die Produktbeschreibung ist etwas "ungünstig".
Der Sensor funktioniert analog und digital, soweit ist alles korrekt.

Digital:
An dem Modul befindet sich ein Potentiometer 0.x-10.5kOhm (Messschwankungen mit Sicherheit vorhanden).
Über dieses Poti lässt sich einstellen wann der digitale Ausgang HIGH geschaltet werden soll.
-> Wenn der eingestellte Wert unterschritten wird schaltet das Modul HIGH auf D.

Analog:
Anders als ich es bisher gewohnt gewesen bin liefert das Modul bei "trocken" (also die Stäbe mit Microfasertuch abgewischt) einen Wert von 1023.
Ich habe den Sensor dann mal in ein volles Glas Leitungswasser gesteckt und einen Wert von ~230 erhalten.
-> So höher der Widerstand, desto höher der Wert (Wobei 2^10 - 1 der höchstmögliche Wert ist)

Insgesamt bin ich zufrieden und werde sicher noch den ein oder anderen Sensor kaufen.
