|
|
The ``ens160`` sensor platform allows you to use your ENS160
|
|
(`datasheet <https://www.sciosense.com/wp-content/uploads/documents/SC-001224-DS-9-ENS160-Datasheet.pdf>`__) air-quality sensors with ESPHome. The :ref:`I²C <i2c>` component is
|
|
required to be set up in your configuration for this sensor to work.
|
|
|
|
.. note::
|
|
|
|
On first power-up of the ENS160 sensor, there is a 1 hour initial startup delay before readings will be available.
|
|
For subsequent starts or reboots, there is a 3 minute warm up period before readings are available. Also, be aware that the
|
|
ENS160 can take up to 1 second for sucessive data measurements to be ready.

|
Configuration variables:
|
|
------------------------
|
|
|
|
- **eco2** (**Required**): Configuration for the eCO2 sensor.
|
|
|
|
- **name** (**Required**, string): The name for the eCO2 sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **tvoc** (**Required**): Configuration for the TVOC sensor.
|
|
|
|
- **name** (**Required**, string): The name for the TVOC sensor.
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor for use in lambdas.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **aqi** (*Optional*): Configuration for the air quality index sensor.
|
|
|
|
- **name** (**Required**, string): The name for the AQI 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``. The update interval should be greater than the measurement
|
|
frequency of the ENS160 which is up to 1 second.
|
|
|
|
Advanced:
|
|
|
|
- **address** (*Optional*, int): Manually specify the I²C address of
|
|
the sensor. Defaults to ``0x53``. Another address can be ``0x52``.
|
|
|
|
- **compensation** (*Optional*): The block containing sensors used for compensation.
|
|
Temperature and humidity compensation improves the accuracy of sensor readings. Without compensation, the
|
|
ENS160 internally assumes 25°C temperature and 50% humidity, with readings noticeably diverting from real changes without compensation in temperature and humidity.
|
|
|
|
- **temperature** (**Required**, :ref:`config-id`): The ID of an external temperature sensor.
|
|
- **humidity** (**Required**, :ref:`config-id`): The ID of an external humidity sensor.
|

Example Text Sensor configuration
|
|
---------------------------------
|
|
|
|
The Air Quality Index(AQI) from this sensor is a number between 1 and 5. The ENS160
|
|
(`datasheet <https://www.sciosense.com/wp-content/uploads/documents/SC-001224-DS-7-ENS160-Datasheet.pdf>`__) states that
|
|
"The AQI-UBA air quality index is derived from a guideline by the German Federal Environmental
|
|
Agency based on a TVOC sum signal". The following is an example configuration to convert the numeric ENS160 AQI to the rating text.
|
|
|
|
.. code-block:: yaml
|
|
|
|
text_sensor:
|
|
- platform: template
|
|
name: "ENS160 Air Quality Rating"
|
|
lambda: |-
|
|
switch ( (int) (id(ens160_air_quality_index).state) ) {
|
|
case 1: return {"Excellent"};
|
|
case 2: return {"Good"};
|
|
case 3: return {"Moderate"};
|
|
case 4: return {"Poor"};
|
|
case 5: return {"Unhealthy"};
|
|
default: return {"Not Available"};
|
|
}
