HDC1080 Temperature+Humidity Sensor
===================================

The HDC1080 Temperature+Humidity sensor allows you to use your HDC1080
(`datasheet <http://www.ti.com/lit/ds/symlink/hdc1080.pdf>`__,
`adafruit <https://www.adafruit.com/product/2635>`__) sensors with
esphomelib. The :ref:`I²C Bus <i2c>` is
required to be set up in your configuration for this sensor to work.

    # Example configuration entry
    sensor:
      - platform: hdc1080
        temperature:
          name: "Living Room Temperature"
        humidity:
          name: "Living Room Pressure"
        update_interval: 15s

Configuration variables:
------------------------

- **temperature** (**Required**): The information for the temperature sensor.

  - **name** (**Required**, string): The name for the temperature sensor.
  - **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
  - All other options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.

- **humidity** (**Required**): The information for the humidity sensor

  - **name** (**Required**, string): The name for the humidity sensor.
  - **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
  - All other options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.

- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``15s``.
  See :ref:`sensor-default_filter`.

Currently, the platform doesn’t support activating the built-in heater,
as it seems to only be rarely of use. If you need it, please open an
issue.
