KNX sensors give a building its information: presence and motion detectors for lighting and climate, temperature, humidity and CO₂ sensors for air quality, light sensors for constant light control, and weather stations for blinds. Their values are shared on the bus, so one sensor can serve several functions.
Compare detection range, mounting (ceiling, wall or flush) and measured values, then add the devices to the project planner.
Frequently asked questions
What is the difference between presence and motion detectors?
Motion detectors react to larger movements such as walking and suit corridors. Presence detectors are sensitive enough to detect a person sitting at a desk and suit offices and meeting rooms.
Where should I mount a presence detector?
Usually on the ceiling, at the height and position the manufacturer gives for its detection range, away from air outlets and heat sources.
Can one sensor control lighting and HVAC?
Yes. On KNX one presence signal can be used by lighting, climate and ventilation at the same time.
