The ``senseair`` sensor platform allows you to use SenseAir CO_2 sensor
|
|
(`website`_) with ESPHome.

SenseAir S8 CO_2 Sensor.

|
|
|
|
As the communication with the SenseAir is done using UART, you need
|
|
to have an :ref:`UART bus <uart>` in your configuration with the ``rx_pin`` connected to the TX pin of the
|
|
sensor and the ``tx_pin`` connected to the RX Pin (it's switched because the
|
|
TX/RX labels are from the perspective of the SenseAir sensor). Additionally, you need to set the baud rate to 9600.

|
Configuration variables:
|
|
------------------------
|
|
|
|
|
|
- **co2** (**Required**): The CO_2 data from the sensor in parts per million (ppm).
|
|
|
|
- **name** (**Required**, string): The name for the CO_2 sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|
|
sensor. Defaults to ``60s``.
|
|
|
|
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
|
|
to use multiple UART buses.
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for actions.

Pins on the SenseAir S8. Only the ones marked with a red circle need to be connected.
|
|
|
|
.. note::
|
|
|
|
``G+`` should be connected to power supply (supported voltage is 4.5 V to 5.25 V), ``G0`` to ``GND`` pin

|
.. _senseair-background_calibration_action:
|
|
|
|
``senseair.background_calibration`` Action
|
|
------------------------------------------
|
|
|
|
This :ref:`action <config-action>` initiates a background calibration on the sensor with the given ID: the current
|
|
CO2 level will be used as a reference for the 400ppm threshold. Ensure that the sensor is in a stable environment with
|
|
fresh ambient air, preferably near a window that has already been opened for a sufficient time.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- senseair.background_calibration: my_senseair_id
|
|
|
|
.. _senseair-background_calibration_result_action:
|
|
|
|
``senseair.background_calibration_result`` Action
|
|
-------------------------------------------------
|
|
|
|
This :ref:`action <config-action>` requests the result of the background calibration procedure from the sensor
|
|
with the given ID. The value will be printed in ESPHome logs.
|
|
|
|
Wait at least one sensor lamp cycle after having triggered the background calibration before requesting its result.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- senseair.background_calibration_result: my_senseair_id
|
|
|
|
.. _senseair-abc_get_period_action:
|
|
|
|
``senseair.abc_get_period`` Action
|
|
----------------------------------
|
|
|
|
This :ref:`action <config-action>` requests the currently configured ABC interval from the sensor with the given ID.
|
|
The value will be printed in ESPHome logs.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- senseair.abc_get_period: my_senseair_id
|
|
|
|
.. _senseair-abc_enable_action:
|
|
|
|
``senseair.abc_enable`` Action
|
|
------------------------------
|
|
|
|
This :ref:`action <config-action>` enables Automatic Baseline Calibration on the sensor with the given ID.
|
|
ABC will be activated with the default interval of 180 hours.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- senseair.abc_enable: my_senseair_id
|
|
|
|
.. _senseair-abc_disable_action:
|
|
|
|
``senseair.abc_disable`` Action
|
|
-------------------------------
|
|
|
|
This :ref:`action <config-action>` disables Automatic Baseline Calibration on the sensor with the given ID.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- senseair.abc_disable: my_senseair_id
