Measure the invisible

Sense includes six smart and advanced sensors that monitor indoor air quality for you. The sensors continuously measure the most important factors that influence your health, comfort, and productivity.

Relative Humidity

Comfort Index: unique Renson calculation

The RENSON COMFORT INDEX is a representation of the ‘comfort’ in a space. Renson uses several sensors to determine a sign of comfort. The Renson Comfort Index is a guide value based on a scientific analysis of factors affecting indoor comfort, such as CO2, temperature, relative humidity, VOCs, noise, and lux.

How does Sense for Professionals work?

A large LED ring and icons on the device itself provide a simple way to show the indoor air quality and when action needs to be taken:  


Air quality and/or comfort = good. No action is required.  


The air quality and/or comfort = average. Please note.  


Air quality and/or comfort = poor. Take action and ventilate the room.
