KEYESTUDIO Turbidity Sensor Module V1 for Arduino,Water Quality Monitor Particles Water/Liquid Turbidity Level Tester

Ich wollte mit dem Trübungssensor einen Fütterungsautomaten für Forellen steuern der bei trübem Wasser die Futtergabe unterbricht. Wie beschrieben sollte dies möglich sein. Ein 3 Volt Microrelais sollte die Steuerung übernehmen. Leider ist die Ausgangsspannung zu gering. Max. 0,2 Volt reichen nicht aus. Eine Anleitung mit Hinweis aus ein Zusatzgerät liegt nicht bei. Eine Anfrage mit der Bitte um Hilfe blieb erfolglos. Für mich ist das Gerät wertlos

接続してすぐデータが取れてんだけどこのデータがどの程度なのかわかんないのが問題。 恐らく、光素子を使ってんだろう低濃度で高電圧となり高濃度だと低電圧になるのだが。 適当にやってもそんな風に動く。 でも、水道水は0%なのかな？5.0Vになってる。 グラフ上0%は、4.2～3Vくらいなんだけどなぁ。 あくまでも目安程度の機器のような気がする。

I saw before I bought it that I couldn't submerge it, so I'm not knocking a star off for that. I think it could be sealed with hot glue, but my guess is that the sensor generates enough heat which might generate condensation. The sensor itself is fantastic and tells you how "clear" the water is. I used example code that D. Porrey posted (Thanks D!) and was up and running quickly. I bought this, along with the TDS sensor to measure the contaminates of my water in my laser cutter cooling system. These two together seem to be a great combo since the readings are consistent and instant. They will tell me when my water is starting to look not so fresh, since it's in a place where I can't see it without some effort. I hooked this up to an arduino and sent the data to Node Red so I have a digital gauge showing my water condition on the phone.

Turbidity vs concentration follows a cubic fit over an extended range, which is convenient. The main issue is that, as noted, the meter is NOT waterproof. It would be nice to have the option to pay more and have that feature!

I originally bought this sensor to use inside my fishtank in order to evaluate the quality of the water. The sensor works great, and I am able to receive readings consistent with test strips. However, the sensor part of this product is not completely water proof. This feels counterintuitive, but I ended up fixing it to a piece of foam as to keep the correct part in the water.
