This multi-sensor combines PIR-based motion detection with precise light measurement in a single DALI-2 certified device, designed for low-bay environments with a large detection area for sensor-based lighting control. It works with D4i LED drivers or luminaires needing only a mains connection, cutting energy use while keeping comfort in line with building regulations. Powered directly from the DALI bus, it needs no separate power supply, and its discreet recessed mount fits standard ceiling installations.
