The ``qmc5883l`` allows you to use your QMC5883L triple-axis magnetometers
|
|
(`datasheet <http://wiki.sunfounder.cc/images/7/72/QMC5883L-Datasheet-1.0.pdf>`__) with
|
|
ESPHome. This sensor is very simular to the :ref:`HMC5883L <hmc5883l>` sensor and is oftern found
|
|
as a knock off replacement. The QMC5883L sensor preforms on par to the HMC5883L sensor,
|
|
though the congiuration differs. 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 I²c 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>`.
|
|
- **field_strength_y** (*Optional*): The field strength in microtesla along the Y-Axis. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **field_strength_z** (*Optional*): The field strength in microtesla along the Z-Axis. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **heading** (*Optional*): The heading of the sensor in degrees. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **range** (*Optional*): The range parameter for the sensor.
|
|
- **oversampling** (*Optional*): The oversampling parameter for the sensor.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
|
|
Range Options
|
|
-------------
|
|
|
|
By default, the QMC5883L sensor measurement range is 200µT. You can, however,
|
|
configure this amount. Possible values:
|
|
|
|
- ``200µT`` (default)
|
|
- ``800µT``
|
|
|
|
Oversampling Options
|
|
--------------------
|
|
|
|
By default, the QMC5883L sensor measures each value 512 times when requesting a new value. You can, however,
|
|
configure this amount. The result is the sensor will take the adverage of the x samples. Possible sampling values:
|
|
|
|
- ``512x`` (default)
|
|
- ``256x``
|
|
- ``128x``
|
|
- ``64x``
