SKYEN is an advanced indoor climate meter, designed to continuously monitor and analyze the indoor climate in a given space. It combines a physical sensor with a digital visualization system and is developed with a focus on simplicity, behavioral design and precision.

Measured parameters

CO₂ (400–5,000 ppm)
Temperature (–40 to 85°C)
Humidity (30–80% RH)
Noise (35–110 dBA)
Brightness (0–30,000 lux)
TVOC (0–65,535 ppb)

Visual feedback

SKYEN uses a color indicator to show the quality of the indoor climate:

Blue light: CO₂ level below 1,000 ppm – the indoor climate is satisfactory.

Red light: CO₂ level above 1,000 ppm – ventilation recommended.

Legislation and sustainability

SKYEN is developed by ÅBN in Denmark and is of course CE marked. SKYEN complies with the following EU directives:

EMC Directive 2014/30/EU
RoHS Directive 2015/863/EU

Products are disposed of in accordance with the WEEE Directive, and ÅBN offers a return scheme as part of our sustainability strategy.

Vejle Municipality

In general, the staff has become more disciplined with the ventilation. They do it more frequently and more routinely than before.

This change in behavior has directly contributed to the impressive results we see here. As a sign of the project's success, fully 70% of the staff would recommend SKYEN to their colleagues in the municipality.

The Org

There is no one who wants to be the grumpy "bus man" who says that now we have to vent. That is why we are happy to be able to give SKYEN that role. Because if people try to contradict the venting, we simply say that "It's not my idea - it's the CLOUD that says we must" and somehow people then accept that the venting is done.

Esbjerg Municipality

Our feedback on the CLOUDS is that people have become much more aware and vent a lot more than they did before. It also means that the heaviness in the head later in the day is not there in the same way.

The idea was that the CLOUD would hang around for three months and then move on to the next location. We have chosen to move away from that, so now people can have the CLOUD for as long as they want.

Vibe school

"The teachers who have had SKYEN think it has been very rewarding to use SKYEN and the teaching material actively in teaching. We have other meters hanging, but the CLOUD is clearly better than meters with numbers"
