|
|
|
The ``HM3301`` sensor platform allows you to use your HM3301 particulate matter sensor
|
|
(`more info <http://wiki.seeedstudio.com/Grove-Laser_PM2.5_Sensor-HM3301>`__)
|
|
sensors with ESPHome.
|
|
|
|
The sensor communicate with board by :ref:`I²C <i2c>` protocol, and requires 3.3v.

|
|
pm_1_0:
|
|
name: "PM1.0"
|
|
pm_2_5:

|
Configuration variables:
|
|
------------------------
|
|
|
|
- **pm_1_0** (*Optional*): Use the concentration of particulates of size less than 1.0µm in µg per cubic meter.
|
|
|
|
- All options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **pm_2_5** (*Optional*): Use the concentration of particulates of size less than 2.5µm in µg per cubic meter.
|
|
|
|
- All options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **pm_10_0** (*Optional*): Use the concentration of particulates of size less than 10.0µm in µg per cubic meter.
|
|
|
|
- All options from :ref:`Sensor <config-sensor>`.
|
|
|
|
- **aqi** (*Optional*): AQI sensor. Requires the ``pm_2_5`` and ``pm_10_0`` sensors defined. See below.
|
|
|
|
- **calculation_type** (**Required**): One of: ``AQI`` or ``CAQI``.
|
|
- All other options from :ref:`Sensor <config-sensor>`.
|
|
|
|
Air Quality Sensor:
|
|
-------------------
|
|
|
|
There is a sensor which calculates quality of air based on PM 2.5 and PM 10.0 values.
|
|
There are two implementations:
|
|
|
|
- AQI: USA air quality standard
|
|
- CAQI: Europe air quality standard
|
|
|
|
.. code-block:: yaml
|
|
|
|
sensor:
|
|
- platform: hm3301
|
|
pm_2_5:
|
|
name: "PM2.5"
|
|
pm_10_0:
|
|
name: "PM10.0"
|
|
aqi:
|
|
name: "AQI"
|
|
calculation_type: "CAQI"
