Future Apple Watches, iPhones could detect pollen levels, air quality, more — Apple World Today

Future Apple Watches, iPhones could detect pollen levels, air quality, even poison gas in the air as evidenced by a newly granted Apple patent (number 10,788,308) for “particulate matter sensors for portable devices.

The device would do this by using a last that could detect particles in the wind flow that reflect and/or scatter laser light. Based on the determined speed and the number of detected particles over time, the particulate matter concentration in the wind flow can be estimated.
