Automatic Wireless Lighting Control
H2-B-CAS Casambi Ceiling PIR Sensor delivers intelligent occupancy detection and daylight sensing for automatic, wireless lighting control.
Smart Presence & Daylight Detection
Powered by a CR123A battery with up to 10 years of battery life, H2-B-CAS combines wireless flexibility with recessed and surface-mounted ceiling installation options, making it ideal for offices, corridors, and retrofit lighting projects.

Supports CR123A battery (10‑year life) or AC 100‑240V wired power.
Advantages of a wireless system (flexibility) without the disadvantages (no battery = no maintenance)
Adjustable detection range (0‑33ft), light level (10‑2000lux), and time delay (3s‑30min).
Recessed mounting (positioning spring) or surface mounting (base with screws).
