The TEMT6000 is an I2C ambient light sensor.

Code Example

Veml7700 sensor;

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

    sensor = new Veml7700(Device.CreateI2cBus());
    sensor.DataSource = Veml7700.SensorTypes.Ambient;

    sensor.RangeExceededHigh += (s, a) => Resolver.Log.Info("Too bright to measure");
    sensor.RangeExceededLow += (s, a) => Resolver.Log.Info("Too dim to measure");

    // classical .NET events can also be used:
    sensor.Updated += (sender, result) => Resolver.Log.Info($"Illuminance: {result.New.Lux:n3}Lux");

    return Task.CompletedTask;
}

public override async Task Run()
{
    var conditions = await sensor.Read();

    Resolver.Log.Info("Initial Readings:");
    Resolver.Log.Info($"  Illuminance: {conditions.Lux:n3}Lux");

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