Light intensity sensor / twilight sensor PHOTASGARD®

Our PHOTASGARD® light intensity sensor respectively light sensor contributes to minimising energy costs for lighting, shading, heating, and cooling. The spectrum of proven applications ranges from daylight-dependent contrast lighting control through motion-dependent control of room functions to presence detection in protected zones and security areas.

This sensor series excels in practical application-oriented measurement ranges, detection ranges and temperature ranges. The enclosure series Frija and Thor ensure the devices’ ergonomic operability and in combination with other sensors and controllers by S+S, demonstrate a self-contained appearance. Versions fitting in with current panel switch programmes are also available upon request.
