Humidity
========
Electronic humidity sensors (hydrometer) measure humidity by measuring the capacitance or resistance of air samples.  This sensor comes packaged with 
the `BME280 <https://ae-bst.resource.bosch.com/media/_tech/media/datasheets/BST-BME280_DS001-11.pdf>`_ integrated environmental unit, only available on 
MetaEnvironment boards, and is accessible through the 
`IHumidityBme280 <http://mbientlab.com/docs/metawear/csharp/1/interfaceMbientLab_1_1MetaWear_1_1Sensor_1_1IHumidityBme280.html>`_ interface.

::

    using MbientLab.MetaWear.Sensor;

    IHumidityBme280 humidity = metawear.GetModule<IHumidityBme280>();

Configuration
-------------
For humidity measurements, oversampling can be used to reduce the noise.  Oversampling modes are set with 
`Configure <http://mbientlab.com/docs/metawear/csharp/1/interfaceMbientLab_1_1MetaWear_1_1Sensor_1_1IHumidityBme280.html#a05e9740812dfbac98bf6f4cc8267522d>`_ method.

::

    using MbientLab.MetaWear.Sensor;
    using MbientLab.MetaWear.Sensor.BarometerBosch;

    import com.mbientlab.metawear.module.HumidityBme280.OversamplingMode;

    // set to ultra high oversampling
    humidity.Configure(Oversampling.UltraHigh);

Humidity Data
-------------
Relative humidity data is a float value from 0 to 100 percent and is represented as a forced data producer.  ::

    await humidity.Percentage.AddRouteAsync(source => 
        source.Stream(data => Console.WriteLine("Humidity = " + data.Value<float>()))
    );
