Astro PIR and Ambient Light Sensor
The Astro PIR and Ambient Light Sensor is a recessed lighting accessory from Astro, designed for discrete motion detection and light-level monitoring in lighting control systems. Its compact, low-profile form is intended for ceilings and panels where architectural subtlety matters.
The sensor has a cylindrical body with a wider, flat flange that sits nearly flush to the mounting surface. The face contains a translucent, multi-faceted dome lens and two small circular openings that house the ambient light sensor and a status indicator, giving a clean, minimal appearance when installed.
Construction uses a matte white plastic housing and spring-loaded metal clips that secure the unit within a recessed cut-out. The spring-clip mechanism enables tool-free installation for a neat, architectural finish in interior ceilings.
The faceted Fresnel-style dome is optimised for passive infrared motion detection while the integrated light sensor monitors ambient lux levels. Together the dual sensing capability lets the unit serve presence detection and light-level control tasks within a larger lighting system, including wireless control platforms where Casambi compatibility is required.
Note the unit is IP20 rated for indoor use only and is supplied with a three-year manufacturer warranty. The product is intended as a control sensor rather than a light source; no lamps or drivers are included.
Lighting Design Online recommends this sensor when you need an unobtrusive presence and light-level input for considered lighting schemes. We provide technical guidance on compatibility and placement so the sensor performs reliably on larger projects, combining professional assurance with clear, project-friendly support.
