Arduino turbidity sensor, How to read value on the serial port?

Using Arduino Programming Questions

Hi, I bought a sensor on amazon (https://amzn.to/2Zeq7q6). I've never used this sensor ... Do you know if it reads analog or digital values? Do I have to make an external circuit or do I just have to connect it 5v, gng, Signal?

Do you know if it reads analog or digital values?Do you know if it reads analog or digital values?

The module outputs an analog signal.

Input voltage VCC: 5 V.
Signal output voltage: 0 ~ 5 V.

Translated form the linked ad.

I have already tried. but it shows no signs of life ... here is the code

void setup() {
Serial.begin(9600);
}

void loop() {
int sensorValue = analogRead(A0);
Serial.println(sensorValue, DEC);
}

Did you try with both clean and dirty water? I looked for a data sheet for that sensor with no success. The best that I found is this AliExpress ad with some details. I never buy anything like that unless I can find a data sheet first.

Do a Google search for "arduino turbidity sensor" to see what others have used, how they were used and some example code.

try adding a delay into that loop. maybe a 500ms delay or so... this loop is going really fast....

I was thinking to buy the same sensor but I found a different turbidity sensor which is much better and has sufficient documentation including arduino code
