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()

        },
        filter: null
    );
    tmp102.Subscribe(consumer);

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