The ``ags10`` sensor platform VOC sensor allows you to use your ASAIR AGS10
|
||
|
|
(`datasheet <http://www.aosong.com/userfiles/files/Datasheet%20AGS10.pdf>`__,
|
||
|
|
`ASAIR`_ ) sensors with
|
||
|
|
ESPHome. The :ref:`I²C Bus <i2c>` is
|
||
|
|
required to be set up in your configuration for this sensor to work.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
The sensor supports up to 15kHz operation, so you should specify up to ``frequency: 15kHz`` in your ``i2c`` configuration.

|
|
Configuration variables:
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
- **tvoc** (**Required**): The information for the total Volatile Organic Compounds sensor.
|
||
|
|
All options from :ref:`Sensor <config-sensor>`.
|
||
|
|
- **address** (*Optional*, int): Manually specify the I²C address of
|
||
|
|
the sensor. Defaults to ``0x1A``.
|
||
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|
||
|
|
sensor. Defaults to ``60s``.
|
||
|
|
- **version** (*Optional*): The firmware version of the sensor.
|
||
|
|
All options from :ref:`Sensor <config-sensor>`.
|
||
|
|

|
|
``ags10.set_zero_point`` Action
|
||
|
|
-------------------------------
|
||
|
|
|
||
|
|
Zero-point of AGS10 has been calibrated before leaving factory. User can re-calibrate the zero-point as
|
||
|
|
needed.

- **id** (**Required**, :ref:`config-id`): The ID of the AGS10 sensor.
|
||
|
|
- **mode** (**Required**, enum): One of supported modes:
|
||
|
|
|
||
|
|
- ``FACTORY_DEFAULT`` - reset to the factory zero-point
|
||
|
|
- ``CURRENT_VALUE`` - set zero-point calibration with current resistance
|
||
|
|
- ``CUSTOM_VALUE`` - set zero-point calibration with resistance pointed with ``value`` option
|
||
|
|
|
||
|
|
- **value** (**Optional**, int): nominated resistance value to set (unit: 0.1 kΩ).

|
``ags10.new_i2c_address`` Action
|
||
|
|
--------------------------------
|
||
|
|
|
||
|
|
I2C address of AGS10 can be modified, and it is possible to use multiple AGS10 sensors on one bus.
|
||
|
|
After sending the command for address changing, the new address is saved and takes effect immediately even
|
||
|
|
after power-off.
