    // classical .NET events can also be used:

    sensor.Subscribe(consumer);

    sensor.StartUpdating(TimeSpan.FromSeconds(2));

    return base.Initialize();

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