The ``qmp6988`` sensor platform allows you to use your QMP6988
|
|
(`datasheet <https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/enviii/QMP6988%20Datasheet.pdf>`__,
|
|
`M5Stack`_) temperature and pressure sensors with ESPHome. The :ref:`I²C <i2c>` is
|
|
required to be set up in your configuration for this sensor to work.

|
|
name: "Living Room Pressure"
|
|
oversampling: 16x

Configuration variables:
|
|
------------------------
|
|
|
|
- **temperature** (*Optional*): The information for the temperature sensor
|
|
|
|
- **oversampling** (*Optional*): The oversampling parameter for the temperature sensor.
|
|
See :ref:`Oversampling Options <qmp6988-oversampling>`.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **pressure** (*Optional*): The information for the pressure sensor.
|
|
|
|
- **oversampling** (*Optional*): The oversampling parameter for the temperature sensor.
|
|
See :ref:`Oversampling Options <qmp6988-oversampling>`.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **address** (*Optional*, int): Manually specify the I²C address of
|
|
the sensor. Defaults to ``0x70``. ``0x56`` is also configurable - see datasheet.
|
|
- **iir_filter** (*Optional*): Set up an Infinite Impulse Response filter to increase accuracy. One of
|
|
``OFF``, ``2x``, ``4x``, ``8x``, ``16x``, ``32x``. Defaults to ``OFF``.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|
|
sensor. Defaults to ``60s``.

Oversampling Options
|
|
--------------------
|
|
|
|
By default, the QMP6988 sensor has been configured to measure each value 8 times when requesting a new value. You can, however,
|
|
configure this amount. Possible oversampling values:
|
|
|
|
- ``NONE`` (value is skipped)
|
|
- ``1x``
|
|
- ``2x``
|
|
- ``4x``
|
|
- ``8x`` (default)
|
|
- ``16x``
|
|
- ``32x``
|
|
- ``64x``
