The XGZP68xx Differential Pressure sensor allows you to use digital differential pressure sensors such as the 6899D
|
|
(`datasheet <https://cfsensor.com/wp-content/uploads/2022/11/XGZP6899D-Pressure-Sensor-V2.8.pdf>`__) or
|
|
6897D Series (`datasheet <https://cfsensor.com/wp-content/uploads/2022/11/XGZP6897D-Pressure-Sensor-V2.7.pdf>`__)
|
|
sensors with ESPHome. The sensors pressure ranges are specified in the datasheets.
|
|
|
|
Calibrating the sensor can be done by checking the value that is returned when
|
|
the ports are open to the air. This value should be 0. If it is not, you can use the offset option to correct the
|
|
reading. For example, if your sensor is reading -40Pa when the ports are disconnected, you can set the offset to 40.

Configuration variables:
|
|
------------------------
|
|
|
|
- **temperature** (*Optional*): All options from :ref:`Sensor <config-sensor>`.
|
|
- **pressure** (*Optional*): All options from :ref:`Sensor <config-sensor>`.
|
|
- **k_value** (*Optional*, int): The K value comes from the datasheet. It will default to 4096 if not specified, which is appropriate for a sensor with a range of +/- 0.5kPa.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``.
