Poor indoor climate is your most expensive invisible expense

THE CLOUD measures CO₂, noise, temperature and air quality – and tells you exactly when to ventilate.
Plug-and-play. No IT setup. Works from day one.

Do you know this?

"It's too hot in here"

Employees are complaining about the temperature. Nobody knows if they are right. SKYEN measures and removes the discussion.

"I always get a headache in the afternoon"

CO₂ above 1,000 ppm noticeably reduces concentration. Most offices exceed this limit daily without realizing it.

"We have a lot of sick days"

Poor air quality is documented as one of the primary causes of sick leave. SKYEN provides you with the data to act on it.

... You're not alone. 1/3 of all companies struggle with the perception of poor indoor climate.

No app. No manual. Just look at the light.

CLOUD

SKYEN is designed to be understood by everyone – students, teachers, caretakers, and care staff. The sensor lights up in three colours and tells you exactly what needs to be done:

🔵 Blue — Good indoor climate
CO₂ below 1,000 ppm. The air is fresh, concentration is high. No action needed.
🔴 Red — Ventilate now
CO₂ above 1,000 ppm. Concentration is noticeably dropping. Open windows and doors.

No WiFi. No app installation. Plug it in, and it works.
