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
