Bosch BMx280 SPI and I2C family of atmospheric sensor

The Bmx280 library is included in the Meadow.Foundation.Sensors.Atmospheric.Bmx280 nuget package and is designed for the Wilderness Labs Meadow .NET IoT platform.

This driver is part of the Meadow.Foundation peripherals library, an open-source repository of drivers and libraries that streamline and simplify adding hardware to your C# .NET Meadow IoT applications.

You can install the library from within Visual studio using the the NuGet Package Manager or from the command line using the .NET CLI:

dotnet add package Meadow.Foundation.Sensors.Atmospheric.Bmx280


protected Bme280 sensor;

protected virtual IPin SpiChipSelect { get; }

public override Task Initialize()


    var consumer = Bme280.CreateObserver(
        handler: result =>
            Resolver.Log.Info($"Observer: Temp changed by threshold; new temp: {result.New.Temperature?.Celsius:N1}C, old: {result.Old?.Temperature?.Celsius:N1}C");
        filter: result =>
            if (result.Old?.Temperature is { } oldTemp &&
                result.Old?.Humidity is { } oldHumidity &&
                result.New.Temperature is { } newTemp &&
                result.New.Humidity is { } newHumidity)
                (newTemp - oldTemp).Abs().Celsius > 0.5 &&
                (newHumidity - oldHumidity).Percent > 0.05;
            return false;

    sensor.Updated += (sender, result) =>
            Resolver.Log.Info($"  Temperature: {result.New.Temperature?.Celsius:N1}C");
            Resolver.Log.Info($"  Relative Humidity: {result.New.Humidity:N1}%");
            Resolver.Log.Info($"  Pressure: {result.New.Pressure?.Millibar:N1}mbar ({result.New.Pressure?.Pascal:N1}Pa)");
        catch (Exception ex)
            Resolver.Log.Error(ex, "Error reading sensor");

    return Task.CompletedTask;

public override async Task Run()
    var conditions = await sensor.Read();
    Resolver.Log.Info("Initial Readings:");
    Resolver.Log.Info($"  Temperature: {conditions.Temperature?.Celsius:N1}C");
    Resolver.Log.Info($"  Pressure: {conditions.Pressure?.Bar:N1}hPa");
    Resolver.Log.Info($"  Relative Humidity: {conditions.Humidity?.Percent:N1}%");


private void CreateSpiSensor()
    Resolver.Log.Info("Create BME280 sensor with SPI...");

    var spi = Device.CreateSpiBus();
    sensor = new Bme280(spi, SpiChipSelect.CreateDigitalOutputPort());

private void CreateI2CSensor()
    Resolver.Log.Info("Create BME280 sensor with I2C...");

    var i2c = Device.CreateI2cBus();
    sensor = new Bme280(i2c, (byte)Bmx280.Addresses.Default); // SDA pulled up
