## Overview

The KEYESTUDIO Turbidity Sensor Module V1 is a compact, Arduino-compatible device designed to measure water turbidity levels from 0% to 3.5% (0-4550 NTU) with high precision (±0.5% error). Operating at 5V and within a wide temperature range (-30℃ to 80℃), it features an adjustable sensitivity potentiometer for customized readings. Ideal for environmental monitoring, wastewater analysis, and research, this lightweight sensor requires partial immersion and careful handling to avoid damage.

## Description

Note: The sensor is not water-proof; can only place the transparent part into water. Be careful not to reversely connect the power supply, or the sensor will be damaged. You can turn the blue potentiometer on the sensor to adjust the sensitivity of sensor. The function of the potentiometer is to change the electrical signal read, and it cannot change the output voltage. Turbidity sensors can be used in measurement of water quality in rivers and streams, wastewater and effluent measurements, sediment transport research and laboratory measurements. Specification: Operating Voltage: DC 5V Operating Current: about 11mA Detection Range: 0%--3.5%（0-4550NTU） Operating Temperature: -30℃~80℃ Storage Temperature：-10℃~80℃ Error Range: ±0.5%F*S Package List: 1 * Turbidity Sensor Module

Review: 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
Review: 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。

## Features

- The turbidity sensor for arduino can detect the water quality by measuring the level of turbidity
- The principle is to convert the current signal into the voltage output through the circuit. The lower the output voltage is, the higher the turbidity value.
- Its detection range is 0%-3.5% (0-4550NTU) , with an error range of ±05%F*S.
- Do not completely immerse the sensor in water. Just measure the small round head of the split parts into the water and measure it. The top of probe is not waterproof.

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.
