- Sensors
- Radon, particulate matter (PM2.5), CO2, temperature, humidity, airborne chemicals (VOC), air pressure
- CO2
- NDIR; 400-5,000 ppm. Airthings' documents differ on accuracy: +/-50 ppm +/-3% (product page), +/-30 ppm +/-3% (help centre) and +/-50 ppm +/-5% (product sheet)
- PM2.5
- Error below 150 ug/m3: +/-(5 ug/m3 + 15%) (maker)
- Radon
- Passive diffusion chamber, alpha spectrometry; 0-500 pCi/L; about 10% accuracy as a 7-day average and 5% over 2 months at 5.4 pCi/L, typical after 30 days of continuous measuring (maker)
- Display
- 2.9-inch e-ink showing up to four values; motion-activated green, yellow or red glow indicator
- Power
- 6 AA batteries (up to 2 years, depending on interval and router) or USB-C for always-on use
- Connectivity
- Wi-Fi 2.4 GHz (802.11b/g/n), Bluetooth Low Energy, Airthings SmartLink; acts as a hub for Airthings Wave devices when on USB-C
