|
|
|
|
The ``sgp40`` sensor platform allows you to use your Sensirion SGP40 VOC sensor
|
|
(`datasheet <https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/9_Gas_Sensors/Sensirion_Gas_Sensors_SGP40_Datasheet.pdf>`__) with ESPHome.
|
|
The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.

# Example configuration entry
|
|
sensor:
|
|
- platform: sgp40
|
|
name: "Workshop VOC"
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **name** (**Required**, string): The name for the CO₂eq sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the sensor. Defaults to ``60s``
|
|
- **store_baseline** (*Optional*, boolean ): Stores and retrieves the baseline information for quicker startups. Defaults to ``True``
|
|
|
|
- **compensation** (*Optional*): The block containing sensors used for compensation. If not set defaults will be used.
|
|
|
|
- **temperature_source** (*Optional*, :ref:`config-id`): Give an external temperature sensor ID
|
|
here. This can improve the sensor's internal calculations. Defaults to ``25``
|
|
|
|
- **humidity_source** (*Optional*, :ref:`config-id`): Give an external humidity sensor ID
|
|
here. This can improve the sensor's internal calculations. Defaults to ``50``
|
|
|
|
- All other options from :ref:`Sensor <config-sensor>`.
