Getting Started

Hardware Setup

1. Connect the SPA06-003 sensor to your Arduino board via I2C:

   • VCC: 3.3V or 5V (depending on your board).
   • GND: Ground.
   • SCL: I2C clock pin.
   • SDA: I2C data pin.

2. Ensure the I2C address matches the sensor configuration (default: 0x77).

Example Code

Basic Pressure and Temperature Reading

#include <Wire.h>
#include "SPL07-003.h"

// Define SPL07-006 I2C address
#define SPL07_ADDR SPL07_ADDR_DEF // Default I2C address (SDO=high)
// #define SPL07_ADDR SPL07_ADDR_ALT // Alternate I2C address (SDO=low)

// Create SPL07-003 sensor instance
SPL07_003 spl;

//HardwareSerial SerialOut(PA10, PA9); //for STM32F103C8Tx

// Runs at startup
void setup() {

  // Begin Serial
  Serial.begin(115200);

  // Configure & start I2C
  //Wire.setSDA(PB7); //for STM32F103C8Tx
  //Wire.setSCL(PB6); //for STM32F103C8Tx
  Wire.begin();

  // Connect to SPL07-003
  if (spl.begin(SPL07_ADDR) == false) {
    Serial.println("Error initializing SPL07-003 :(");
    while (1) {}
  }//if
  Serial.println("Connected to SPL07-003! :)");

  // Set pressure & temperature sampling settings
  spl.setPressureConfig(SPL07_4HZ, SPL07_32SAMPLES);
  spl.setTemperatureConfig(SPL07_4HZ, SPL07_1SAMPLE);

  // Set SPL07-003 to continuous measurements
  spl.setMode(SPL07_CONT_PRES_TEMP);

}//setup()


// Runs continuously
void loop() {

  // Wait for available reading
  if (spl.pressureAvailable() || spl.temperatureAvailable()) {
    // Read latest values
    double pres = spl.readPressure();
    double temp = spl.readTemperature();
    double altitude = spl.calcAltitude();
    // Print to serial
    Serial.print("Pres: ");
    Serial.print(pres, 3);
    Serial.print(" Pa, Temp: ");
    Serial.print(temp, 3);
    Serial.print(" C, Altitude: ");
    Serial.print(altitude, 3);
    Serial.println(" m");
  }//if

}//loop()

API Reference

Initialization

• bool begin(uint8_t addr = SPL07_ADDR_DEF, TwoWire *wire = &Wire, uint8_t id = SPL07_EXPECTED_ID);
  • Initializes the sensor and reads calibration coefficients.
  • Returns true if successful, false otherwise.

Measurement

• double readPressure();
  • Reads the current pressure in Pascals (Pa).
• double readTemperature();
  • Reads the current temperature in degrees Celsius (°C).
• double calcAltitude();
  • Calculate altitude (M).

Configuration

• void setMode(SPL07_Modes mode);
  • Set the sensor mode.
• void setPressureConfig(SPL07_Measure_Rates rate, SPL07_Oversample_Rates oversample);
  • Configures pressure oversampling and measurement rate.
• void setTemperatureConfig(SPL07_Measure_Rates rate, SPL07_Oversample_Rates oversample);
  • Configures temperature oversampling and measurement rate.
• void setTemperatureSource(SPL07_Temperature_Source src);
  • Configure the source of the temperature sensor.

Interrupts

• void setInterruptActiveHigh(bool activeHigh);
  • Sets if the interrupt pin should function as active high or active low.
• void configureInterrupt(SPL07_Interrupt_Options opt);
  • Configures the interrupt function
• uint8_t getInterruptStatus();
  • Returns the current interrupt register value annd resets the interrupt status register when run.
