The TMP102 is a temperature sensor capable of reading the current temperature with an accuracy of 0.5C over the range of -25C to 85C with a total range of -40C to 125C.

Code Example​

Tmp102 tmp102;

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

    tmp102 = new Tmp102(Device.CreateI2cBus());

    var consumer = Tmp102.CreateObserver(
        handler: result =>
        {
            Resolver.Log.Info($"Temperature New Value {result.New.Celsius}C");
            Resolver.Log.Info($"Temperature Old Value {result.Old?.Celsius}C");
        },
        filter: null
    );
    tmp102.Subscribe(consumer);

    tmp102.Updated += (object sender, IChangeResult<Meadow.Units.Temperature> e) =>
    {
        Resolver.Log.Info($"Temperature Updated: {e.New.Celsius:N2}C");
    };

    return Task.CompletedTask;
}

public override async Task Run()
{
    var temp = await tmp102.Read();
    Resolver.Log.Info($"Current temperature: {temp.Celsius} C");

    tmp102.StartUpdating(TimeSpan.FromSeconds(1));
}
