Air Quality	Instructions on how to add air quality sensors with Home Assistant	0.85	air_quality	internal		@home-assistant/core	entity

The air_quality base platform allows other integrations to process information about air quality and pollution details. It is used by integrations that provide an air_quality sensor - you can find those under the health integrations.

The platforms cover the following levels (if they are available):

• The particulate matter 0.1 (<= 0.1 μm) level.
• The particulate matter 2.5 (<= 2.5 μm) level.
• The particulate matter 10 (<= 10 μm) level.
• The Air Quality Index (AQI).
• The O3 (ozone) level.
• The CO (carbon monoxide) level.
• The CO2 (carbon dioxide) level.
• The SO2 (sulphur dioxide) level.
• The N2O (nitrogen oxide) level.
• The NO (nitrogen monoxide) level.
• The NO2 (nitrogen dioxide) level.
