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
|
|
ESPHome. 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>`.
|
|
- **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>`.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
|
|
- **oversampling** (*Optional*): Number of readings to average over for each sample. One of ``1x``, ``2x``,
|
|
``4x``, ``8x``. Defaults to ``1x``.
|
|
- **range** (*Optional*): Select a range / gain preset. This does not affect the scale of the values published
|
|
but allows one to avoid overflows at the cost of reading resolution. Supported values are 88µT, 130µT, 190µT,
|
|
250µT, 400µT, 470µT, 560µT, 810µT. Default range is ±130µT.
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
