Lis2Mdl sensor;

public override Task Initialize()

    sensor = new Lis2Mdl(Device.CreateI2cBus());

    // classical .NET events can also be used:
    sensor.Updated += HandleResult;

    // Example that uses an IObservable subscription to only be notified when the filter is satisfied
    var consumer = Lis2Mdl.CreateObserver(handler: result => HandleResult(this, result),
                                         filter: result => FilterResult(result));

    sensor.Subscribe(consumer);

    sensor.StartUpdating(TimeSpan.FromMilliseconds(2000));

    return base.Initialize();
}

bool FilterResult(IChangeResult<MagneticField3D> result)
{
    return result.New.Z > new MagneticField(0.1, MagneticField.UnitType.Gauss);
}

void HandleResult(object sender,
    IChangeResult<MagneticField3D> result)
{
    var mag = result.New;

    Resolver.Log.Info($"MagX={mag.X.Gauss:0.##}gauss, MagY={mag.Y.Gauss:0.##}gauss, GyroZ={mag.Z.Gauss:0.##}gauss");
