#define data_pin A0

// 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() {

  int sensorValue = analogRead(data_pin);          // read the input on analog data_pin

  float voltage = sensorValue * (5.0 / 1023.0);     // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):

  float pressure = map(voltage,0.5,4.5,0,16);    //ELWPs16   0-16 bar

   // print the results to the Serial Monitor:

  Serial.print("Pressure = ");

  Serial.println(pressure);

  // wait 2 milliseconds before the next loop 

  delay(2);
