Usage

private Bh1900Nux _sensor;

public override Task Initialize()
{
    Resolver.Log.Info("Initializing...");

    _sensor = new Bh1900Nux(Device.CreateI2cBus(), Bh1900Nux.Addresses.Default);

    var consumer = Bh1900Nux.CreateObserver(
        handler: result =>
        {
            Resolver.Log.Info($"Observer: Temp changed by threshold; new temp: {result.New.Celsius:N2}C, old: {result.Old?.Celsius:N2}C");
        },
        filter: result =>
        {
            if (result.Old is { } old)
            {
                return (result.New - old).Abs().Celsius > 0.5;
            }
            return false;
        }
    );
    _sensor.Subscribe(consumer);

    _sensor.Updated += (sender, result) =>
    {
        Resolver.Log.Info($"  Temperature: {result.New.Celsius:N2}C");
    };

    return Task.CompletedTask;
}

public async override Task Run()
{
    var conditions = await _sensor.Read();
    Resolver.Log.Info("Initial Readings:");
    Resolver.Log.Info($"  Temperature: {conditions.Celsius:N2}C");

    _sensor.StartUpdating(TimeSpan.FromSeconds(1));
}
