- The LPS331AP Pressure/Altitude Sensor Carrier with Voltage Regulator is an I2C-based sensor that can be used with a variety of microcontrollers. In this example, I'll provide you with an Arduino code to read the pressure and altitude from the sensor. Note that this code assumes you are using an Arduino Uno or a similar board.
- First, connect the sensor to the Arduino as follows:
- VIN to 5V
- GND to GND
- SDA to A4 (on Arduino Uno) or the dedicated SDA pin on other boards
- SCL to A5 (on Arduino Uno) or the dedicated SCL pin on other boards
- You will also need to install the "LPS331" library by Pololu in the Arduino IDE. You can find this library in the Library Manager or download it from the following link: https://github.com/pololu/lps-arduino/archive/master.zip
- Upload this code to your Arduino and open the Serial Monitor. The sensor will output pressure in millibars and altitude in meters every second.

- void setup() {
- Serial.begin(9600); // Initialize the serial communication

- if (!lps.init()) {
- Serial.println("Failed to initialize the LPS331AP sensor");
- while (1); // Halt the program if the sensor is not detected
- }
- lps.enableDefault(); // Enable default settings
- }
- void loop() {
- float pressure = lps.readPressureMillibars(); // Read pressure in millibars
- float altitude = lps.pressureToAltitudeMeters(pressure); // Convert pressure to altitude in meters
- Serial.print("Pressure: ");
- Serial.print(pressure);
- Serial.print(" mbar, Altitude: ");
- Serial.print(altitude);
- Serial.println(" meters");
- delay(1000); // Wait for 1 second before reading the sensor again
