TCS34725 RGB Color Sensor
=========================

The ``tcs34725`` sensor platform allows you to use your TCS34725 RGB color sensors
(`datasheet <https://cdn-shop.adafruit.com/datasheets/TCS34725.pdf>`__,
`Adafruit`_) temperature and pressure sensors with esphomelib. The :ref:`I²C <i2c>` is
required to be set up in your configuration for this sensor to work.

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

- **red_channel** (*Optional*): Get the percentage of how strongly the red color channel is activated.
  All options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **green_channel** (*Optional*): Get the percentage of how strongly the green color channel is activated.
  All options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **blue_channel** (*Optional*): Get the percentage of how strongly the blue color channel is activated.
  All options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **clear_channel** (*Optional*): Get the percentage of how strongly the clear (without a color filter)
  channel is activated. All options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **illuminance** (*Optional*): Get the total illuminance of the sensor in lx.
  All options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **color_temperature** (*Optional*): Get the calculated color temperature of the light in Kelvin.
  All options from :ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **gain** (*Optional*): Set the gain for the internal ADCs to work better in certain low-light conditions. Valid
  values are ``1x`` (default), ``4x``, ``16x``, ``60x`` (highest gain).
- **integration_time** (*Optional*): The amount of time the light sensor is exposed. Valid values are
  ``2.4ms`` (default), ``24ms``, ``50ms``, ``101ms``, ``154ms``, ``700ms``.
- **address** (*Optional*, int): Manually specify the i^2c address of the sensor. Defaults to ``0x29``.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
  sensor. Defaults to ``15s``. See :ref:`sensor-default_filter`.
