PIR, lux, and Casambi in a single ultra-slim ceiling unit. The Unity S1 is designed for commercial interiors where sensor hardware needs to be discreet — the low-profile body blends into office and hospitality ceilings without drawing attention. All parameters are configured wirelessly from the Casambi app.
Key Benefits
The Unity S1's low-profile form factor sits flush to the ceiling without protruding or drawing attention. Suited to high-end office fit-outs, hotel rooms, and retail spaces where aesthetic continuity matters.
Combines passive infrared occupancy detection with ambient lux measurement. A single ceiling sensor enables both auto-off on vacancy and daylight harvesting — no additional hardware required.
Joins the Casambi mesh instantly on power. Works with any Casambi luminaire, driver, or keypad on the same network. Configured entirely from the Casambi app — no separate sensor software.
