It measures PM2.5, VOCs, temperature, and humidity, displaying a colored LED ring that shifts from blue (clean) to red (unhealthy). The pin is 3 cm in diameter, made from brushed brass with a subtle etched pattern. The back has a standard pin clasp for attaching to clothing, plus a kickstand for desk use. A small fan inside pulls air samples continuously. Battery lasts 2 days.
