Tutorial: How to Use Absolute Pressure Sensor MD-PS002-150KPaA

The absolute pressure sensor MD-PS002-150KPaA is ideal for measuring atmospheric pressure or fluids in various fields such as meteorology, industrial automation, and DIY projects. It is suitable for both beginners and more experienced makers who want to add pressure monitoring functionality to their Arduino devices.

What you need

• Arduino Uno or compatible
• USB cable to connect the Arduino to the PC
• Absolute Pressure Sensor MD-PS002-150KPaA

Steps

1. Connect the sensor to pins A0, VCC, and GND of the Arduino using jumper wires.
2. Open Arduino IDE and create a new sketch.
3. Insert the code to read the sensor value.
4. Save the sketch with a meaningful name such as ‘AbsolutePressure’.
5. Upload the sketch to the Arduino via USB.
6. Open the Serial Monitor window in Arduino IDE.
7. Set the transmission speed to 9600 baud.
8. Read the pressure values displayed in the Serial Monitor.

Example code

const int sensorPin = A0;

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

void loop() {
 int sensorValue = analogRead(sensorPin);
 float voltage = (sensorValue / 1024.0) * 5.0;
 // Verifica sul datasheet per la conversione da tensione a pressione
 Serial.println(voltage);
 delay(1000);
}

Mini project

Create an alarm system that sends an email notification when the atmospheric pressure exceeds a certain critical value.

Common mistakes

• Do not verify the correct pin connections.
• Omit the installation of the necessary library to read the sensor values.
• Ignore the voltage to pressure conversion defined in the datasheet.
• Do not properly configure the transmission speed in Serial Monitor.

Recommended accessories

• ESP8266 Wi-Fi Module
• LCD Display for Arduino
• Portable Batteries for External Power Supply

Frequently asked questions

How can I convert the analog value to pressure?
Check the sensor’s datasheet to find the relationship between voltage and pressure.
