Many smart home functions require reliable human presence sensors and light level measurement in a room. This is achieved with combined occupancy motion and light sensors.
Unfortunately, most of these sensors are quite large and bulky and look rather awful on the ceiling. Most of them do not integrate smoothly and unobtrusively into otherwise ambitious and aesthetically pleasing interior fitouts. This is exactly where occy® Smart Home Motion Sensors play out their strengths.
In some smart home projects the 24V ecos occupancy motion sensors with potential free / volt free output can be a good choice.
