HMC5883L Magnetometer
=====================
The ``hmc5883l`` allows you to use your HMC5883L triple-axis magnetometers
(`datasheet <https://cdn-shop.adafruit.com/datasheets/HMC5883L_3-Axis_Digital_Compass_IC.pdf>`__,
`Adafruit`_) with
esphomelib. The :ref:`I²C Bus <i2c>` is
required to be set up in your configuration for this sensor to work.

Configuration variables:
------------------------
- **address** (*Optional*, int): Manually specify the i^2c address of the sensor. Defaults to ``0x1E``.
- **field_strength_x** (*Optional*): The field strength in microtesla along the X-Axis. All options from
:ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **field_strength_y** (*Optional*): The field strength in microtesla along the Y-Axis. All options from
:ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **field_strength_z** (*Optional*): The field strength in microtesla along the Z-Axis. All options from
:ref:`Sensor <config-sensor>` and :ref:`MQTT Component <config-mqtt-component>`.
- **heading** (*Optional*): The heading of the sensor in degrees. All 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`.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
