Programming​

#include <Adafruit_BMP280.h> // http://librarymanager/All#Adafruit_BMP280_Library
#include <SPI.h>

Adafruit_BMP280 bmp;

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

void loop() {
    Serial.print("Pressure: ");
    Serial.println(bmp_sensor.readPressure());
    Serial.print("Temperature: ");
    Serial.println(bmp_sensor.readTemperature());
    Serial.print("Altitude: ");
    Serial.println(bmp_sensor.readAltitude(1013));
}

Programming (Blockly)​

In Blockly, the sensor can be read using the following block:

In the block, you can select between the different parameters of the air pressure/temperature sensor:

  • Air pressure in Pascal (Pa)
  • Temperature in Celsius (°C)
  • Altitude above sea level in meters (a reference air pressure is required)
