Code:

int sensorPin = A0; // select the input pin for the potentiometer
int buzzer = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor

void setup()
{
  pinMode(buzzer, OUTPUT);

}

void loop() {
  sensorValue = analogRead(sensorPin);
  Serial.println(sensorValue);
  if (sensorValue < 40) {
    tone(buzzer, 1000);
  }
  else {
    noTone(buzzer);
  }
}
