HTS221 Module
*************

This module contains the driver for STMicroelectronics HTS221 temperature and relative humidity sensor. Its highlight is that it outputs its measurement in a 16-bit resolution and has a high rH sensitivity of 0.004% (`datasheet <http://www.st.com/content/ccc/resource/technical/document/datasheet/4d/9a/9c/ad/25/07/42/34/DM00116291.pdf/files/DM00116291.pdf/jcr:content/translations/en.DM00116291.pdf>`_).
    
.. class:: HTS221(drvsel,int_pin,address=0x5F,clk=400000)

    Creates an intance of a new HTS221.

    :param drvsel: I2C Bus used `( I2C0, I2C0 )`
    :param int_pin: Interrupt pin used for events
    :param address: Slave address, default 0x5f
    :param clk: Clock speed, default 400kHz

    Example: ::

        from stm.hts221 import hts221

        temp_hum = hts221.HTS221( I2C1,D31 )
        temp, hum = temp_hum.get_temp_humidity()

    
.. method:: get_temp_humidity()

        Retrieves both temperature and humidity in one call.

        Returns temp, humidity
