I love this device, and the world of citizen science.
The AirBeam2 is a portable device that measures air quality, created by the nonprofit called HabitMap. The AirBeam2 is part of a citizen science project called AirCasting, which is an online mapping system that displays air quality measurements from AiBeam2 users.
