Cheap air quality measurements targeted by new wearable sensor
Popular Science recently reported on a wearable air quality monitor designed and prototyped by electrician, Kevin Hart, and nurse, Laura Moe. They are targeting a late fall 2015 release at a price point of $100 (US).
From the article, "A fan directly beneath TZOA’s triangular cover sucks in air. As pollutants cross a laser, they scatter light onto a sensor that counts them. TZOA then glows a color corresponding to the air safety level. A smartphone app also displays that data, along with daily UV light exposure and crowdsourced pollution maps."
