I came across this site today. It’s a project where a team is working on a device to have in your home that detects amounts of pollen and other particulates in the air. This could help those sensitive to air pollutants to know what is bothering them. I think it would be really interesting to have that kind of data, but maybe not at the $350 price tag listed in their survey. I happen to be allergic to almost everything outside so I’m not sure how knowing those allergens are present would help me. What’s really interesting is how this data could possibly supplement data collected nationally. It’d be kind of like a home weather station, only an allergy station.
