|
|
|
|
The ``scd30`` sensor platform allows you to use your Sensiron SCD30 CO₂
|
|
(`datasheet <https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/9.5_CO2/Sensirion_CO2_Sensors_SCD30_Datasheet.pdf>`__) sensors with ESPHome.
|
|
The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.

Configuration variables:
|
|
------------------------
|
|
|
|
- **co2** (**Required**): The information for the CO₂ sensor.
|
|
|
|
- **name** (**Required**, string): The name for the CO₂eq sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **temperature** (**Required**): The information for the Temperature sensor.
|
|
|
|
- **name** (**Required**, string): The name for the temperature sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
|
|
- **humidity** (**Required**): The information for the Humidity sensor.
|
|
|
|
- **name** (**Required**, string): The name for the humidity sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **temperature_offset** (*Optional*, float): Temperature and humidity
|
|
offsets may occur when operating the sensor in end-customer
|
|
devices. This variable allows the compensation of those effects by
|
|
setting a temperature offset.
|
|
|
|
- **automatic_self_calibration** (*Optional*, bool): Whether to enable
|
|
automatic self calibration (ASC). Defaults to ``true``.
|
|
|
|
- **ambient_pressure_compensation** (*Optional*, int): Enable compensation
|
|
of measured CO₂ values based on given ambient pressure in mBar.
|
|
|
|
- **altitude_compensation** (*Optional*, int): Enable compensating
|
|
deviations due to current altitude (in metres). Notice: setting
|
|
*altitude_compensation* is ignored if *ambient_pressure_compensation*
|
|
is set.
|
|
|
|
- **address** (*Optional*, int): Manually specify the I²C address of the sensor.
|
|
Defaults to ``0x61``.
|
|
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|
|
sensor. Defaults to ``60s``.
