KIE-TS-300B turbidity sensor not working

Using Arduino Sensors
1

I'm working with a clone Arduino micro board, I've got the color sensor up and running fine. So the problem isn't the card.

I'm using the example code, just to try out the module:

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  // print out the value you read:
  Serial.println(sensorValue);
  delay(1);  // delay in between reads for stability
}

A0 is on the output, ground and 5V wires are setup right. The red light on the module is red. I'm getting readings about 200-ish. That's about 1.5V if I convert it. I can't block it with an opaque object, that doesn't change the readings. I removed the cover, to see if it helps, still the same. I've tried three different sensors.

The one I'm using is this device: https://www.elecrow.com/ts-300b-turbidity-sensor-water-turbidity-module-turbidity-detection-module.html

Any suggestions as to how and why is this happening, thank you.
