Usage

Bh1750 sensor;

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

    var i2c = Device.CreateI2cBus();
    sensor = new Bh1750(
        i2c,
        measuringMode: Mode.ContinuouslyHighResolutionMode, // the various modes take differing amounts of time.
        lightTransmittance: 1 // lower this to increase sensitivity, for instance, if it's behind a semi opaque window
        ); 

    // Example that uses an IObservable subscription to only be notified when the filter is satisfied
    var consumer = Bh1750.CreateObserver(
        handler: result => Resolver.Log.Info($"Observer: filter satisfied: {result.New.Lux:N2}Lux, old: {result.Old?.Lux:N2}Lux"),
        
        // only notify if the visible light changes by 100 lux (put your hand over the sensor to trigger)
        filter: result => {
            if (result.Old is { } old) { //c# 8 pattern match syntax. checks for !null and assigns var.
                // returns true if > 100lux change
                return ((result.New - old).Abs().Lux > 100);
            }
            return false;
        });
    sensor.Subscribe(consumer);

    // classical .NET events can also be used:
    sensor.Updated += (sender, result) => Resolver.Log.Info($"Light: {result.New.Lux:N2}Lux");

    return Task.CompletedTask;
}

public override async Task Run()
{
    var result = await sensor.Read();
    Resolver.Log.Info("Initial Readings:");
    Resolver.Log.Info($" Light: {result.Lux:N2}Lux");

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