I have problems with the input of my sensor

Hello, I have a humidity sensor, and I make this code:

||void setup() {
Serial.begin(57600);

}

void loop() {
Serial.print("Porcentaje de humedad1: ");
Serial.println(analogRead(A0));
delay(100);

}

but the analogRead give 3900,3685, etc insted of the 0-1024, What could be the problem?

Caveat emptor...
