const int analogInPin = A0; // Analog input pin that the potentiometer is attached to

int sensorValue = 0; // value read from the pressure sensor via the amplifier stage
float outputValue = 0; // value output to the Serial port or LCD display

void setup() 
{
// initialize serial communications at 9600bps
Serial.begin(9600); 
}

void loop() 
{
// read the analog in value:
sensorValue = analogRead(analogInPin); 
outputValue = map(sensorValue, 10, 1023, 0, 100); //The zero value of sensor is around 10

// print the results to the serial monitor:
Serial.print("sensor = " ); 
Serial.print(sensorValue); 
Serial.print("\toutput = "); 
Serial.println(outputValue);

// wait 500 milliseconds before the next loop
// for the analog-to-digital converter to settle
// after the last reading:
