Alexa can now tell you how clean the air is that you are breathing. For the Umweltbundesamt we built a Skill for Amazon Alexa. It uses current, official data gathered by over 300 UBA measuring stations and shows contaminants like fine particulate matter (PM₁₀), nitrogen dioxide (NO₂) and ozone (O₃) and based on them the air quality index (LQI) for a given time and location. Historical data of recent days and weeks is also available.
This skill is availabe in German. It also provides information about air quality, substances in the air, recommendations for outdoor activities based on the air quality index and recommendations for allergy sufferers.
The skill is available from Amazon and can be activated with the phrase “Meine Luft”.
