VCC - 5V
S   - Analog pin0

Example code

int sensorValue;
void setup()
 Serial.begin(9600);      // sets the serial port to 9600
void loop()
 sensorValue = analogRead(0);       // read analog input pin 0
 Serial.println(sensorValue, DEC);  // prints the value read
 delay(100);                        // wait 100ms for next reading
