An additional part to be located in an air vent and an air vent (102) for a ventilation system comprising a number of elements, which air vent lets air enter the ventilation system and/or move away from the ventilation system. The additional part (102) of air vent comprises one or several sensors measuring parameters related to air quality, a data transfer interface for implementing data transfer between said air vent and other elements of said ventilation system, and a processing unit which is automatically configured to determine changes needed in the settings of said ventilation system on the basis of parameters measured by said sensors and send information on said changes needed in the other elements of said ventilation system through said data transfer interface. |
