Usage

Ms5611 sensor;

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

    sensor = new Ms5611(Device.CreateI2cBus());

    var consumer = Ms5611.CreateObserver(
        handler: result =>
        {
            Resolver.Log.Info($"Observer: Temp changed by threshold; new temp: {result.New.Temperature?.Celsius:N2}C, old: {result.Old?.Temperature?.Celsius:N2}C");
        },
        filter: result =>
        {
            if (result.Old is { } old)
            {
                return (
                (result.New.Temperature.Value - old.Temperature.Value).Abs().Celsius > 0.5
                &&
                (result.New.Pressure.Value - old.Pressure.Value).Millibar > 0.5
                );
            }
            return false;
        }
    );
    sensor.Subscribe(consumer);

    sensor.Updated += (sender, result) =>
    {
        Resolver.Log.Info($"  Temperature: {result.New.Temperature?.Celsius:N2}C");
        Resolver.Log.Info($"  Pressure: {result.New.Pressure?.Millibar:N2}mbar ({result.New.Pressure?.Pascal:N2}Pa)");
    };

    return Task.CompletedTask;
}

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

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