The TEMT6000 is an analog ambient light sensor.

Code Example

Temt6000 sensor;

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

    // configure our sensor
    sensor = new Temt6000(Device.Pins.A03);

    // Example that uses an IObservable subscription to only be notified when the voltage changes by at least 0.5V
    var consumer = Temt6000.CreateObserver(
        handler: result => Resolver.Log.Info($"Observer filter satisfied: {result.New.Volts:N2}V, old: {result.Old?.Volts:N2}V"),
        // only notify if the change is greater than 0.5V
        filter: result =>
        {
            if (result.Old is { } old)
            {
                return (result.New - old).Abs().Volts > 0.5; // returns true if > 0.5V change.
            }
            return false;
        });

    sensor.Subscribe(consumer);

    // classical .NET events can also be used:
    sensor.Updated += (sender, result) =>
    {
        Resolver.Log.Info($"Voltage Changed, new: {result.New.Volts:N2}V, old: {result.Old?.Volts:N2}V");
    };

    return Task.CompletedTask;
}

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

    sensor.StartUpdating(TimeSpan.FromMilliseconds(1000));
}

Wiring Example

To wire a Temt6000 to your Meadow board, connect the following:

Temt6000	Meadow Pin
GND	GND
SIG	A03
VCC	3V3

It should look like the following diagram:
