Combined 5.8 GHz microwave occupancy detection and lux measurement in a single ceiling unit with embedded Casambi. The MC177S-B1 handles both presence-based switching and daylight harvesting — reducing wiring complexity and ceiling penetrations versus using two separate devices. Ideal for perimeter zones with window light contribution.
Key Benefits
The integrated lux sensor measures available daylight and dims artificial lighting proportionally. As natural light increases, the Casambi network automatically reduces power — maximising energy savings in perimeter zones.
Microwave occupancy and lux measurement in a single ceiling fitting. Fewer ceiling penetrations, fewer SKUs to procure, and a cleaner installation versus running separate occupancy and daylight sensors.
Both the hold time and the daylight threshold are configured from the Casambi app. Adjust the target lux level, sensitivity, and linked groups without accessing the ceiling or using separate software.
