Exposure to air pollution and other airborne hazards contributes to respiratory and cardiovascular issues, diseases, allergies, and premature death for tens of millions of people each year. Poor air quality can also impair the enjoyment of indoor and outdoor activities. As a result, there is a need to monitor air quality in real-time and warn people of any local hazards.

This publication describes systems and techniques for portable electronic devices, such as smartphones, tablets, laptops, and smartwatches, to measure and analyze local air quality. For example, a portable electronic device detects potential airborne hazards using a volatile-organic-compound (VOC) sensor and/or a particulate matter (PM) sensor. The portable electronic device, using an on-device machine-learned model, evaluates the measured data to generate appropriate alerts for the user.
