Contoh Pembacaan Sensor MPX5050DP dengan Arduino, untuk mengukur ketinggian air/ volume dalam suatu tangki :

Rangkaian dengan Arduino :

Script Code Versi 1 :

// Catatan : nilai berikut ini perlu dirubah untuk mengkalibrasi/ menggunakan tipe sensor dengan kemampuan baca yang berbeda.

// 50kPa = 5.10 mH20 (meter of water column) max water column depth (http://www.convert-measurement-units.com/conversion-calculator.php?type=pressure)

// If max v of 4.5v = 50kPa, then sensorValue of 921 (920.7) = 50kPa

int sensorPin = A0;

int sensorValue = 0, sensorMax = 1023, sensorOffset = 52;

float voltage = 0, kpa = 0, voltageMax = 5.0, kpaRangeTopVoltage = 4.5;

void setup() {

Serial.begin(9600);

}

void loop() {

sensorValue = analogRead(sensorPin) – sensorOffset; // Read sensor & adjust with offset

Serial.print(“sensorValue (offset “);

Serial.print(sensorOffset, DEC);

Serial.print(“): “);

Serial.println(sensorValue, DEC);

if (sensorValue == 0) {

kpa = 0;

voltage = 0;

} else {

voltage = sensorValue * (voltageMax / sensorMax);

kpa=((voltage/kpaRangeTopVoltage)-0.04)/0.018;

}

Serial.print(“voltage: “);

Serial.println(voltage, 3);

Serial.print(“kpa: “);

Serial.println(kpa, 1);

Serial.println(“”);

delay(1000);

}

Script Code Versi 2 :

// Pin 1 (notch) – Analog output
// Pin 2 – Gnd
// Pin 3 – 5V

int sensorPin = A0; // Select input pin for the potentiometer
// int sensorValue = 0; // Variable stores value coming from the sensor
double sensorValue = 0;
double voltage = 0;
double kpa = 0;

void setup() {
Serial.begin(9600);
}

void loop() {
// sensorValue = analogRead(sensorPin); // Read sensor
sensorValue = (double) analogRead(sensorPin);
Serial.print(“sensorValue: “);
Serial.println(sensorValue, 1); // Display result

voltage = sensorValue * (5.0 / 1023.0);
Serial.print(“voltage: “);
Serial.println(voltage, 1); // Display result

kpa=((voltage/5.0)-0.04)/0.018;
Serial.print(“kpa: “);
Serial.println(kpa, 1); // Display result

Serial.println(“”);
delay(1000); // Wait 400 milliseconds
}
