A BME280 device.
To use the node in your project you should have the wayland/bme280-barometer library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
C++ implementation
// Tell XOD where it could download the library:
#pragma XOD require "https://github.com/adafruit/Adafruit_Sensor"
#pragma XOD require "https://github.com/adafruit/Adafruit_BME280_Library"
#pragma XOD require "https://github.com/adafruit/Adafruit_BusIO"
//Include C++ libraries
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

using Type = Adafruit_BME280*;

Adafruit_BME280 sensor = Adafruit_BME280();

// It should be evaluated only once on the first (setup) transaction
