Aranet4 PRO professional CO₂ sensor, EU868 (mk2, SenseAir)

The professional version of Aranet4: the same measurements, plus Aranet radio to the Aranet PRO base station, for offices, schools and buildings with several sensors. It also works on its own over Bluetooth with the Aranet Home app.

One Aranet PRO base station collects data from up to 100 sensors, within up to 3 km line of sight, and stores it for up to 10 years. Without a base station, Aranet4 PRO works just like an Aranet4 HOME, from your phone.
