HTU21D Temperature/Humidity Sensor
==================================

The HTU21D component allows you get accurate temperature and humidity readings from your HTU21D
(`datasheet <https://cdn-shop.adafruit.com/datasheets/1899_HTU21D.pdf>`_,
`adafruit <https://www.adafruit.com/product/1899>`_) sensors with esphomelib. To use these
i2c-based devices, first initialize the i2c bus using the pins you have for SDA and SCL and
then create the sensors themselves as in below example.

Example Usage
-------------

.. code-block:: cpp

    // inside setup()
    App.init_i2c(SDA_PIN, SCL_PIN); // change these values for your pins.
    // create sensors
    App.make_htu21d_sensor("Outside Temperature", "Outside Humidity");

.. cpp:namespace:: nullptr

See :cpp:func:`Application::make_htu21d_sensor`.
