PHOTASGARD
The room light intensity sensor PHOTASGARD
intensity and is used to control luminaries, lighting systems, Venetian blinds and
canvas blinds, etc., to monitor lighting conditions at workplaces, in storage halls,
workshops and corridors, in indoor areas, in industrial halls, in offices as well as in
residential and business facilities, for daylight-dependant constant light control,
as light intensity or twilight sensor and to control sunshade equipment avoiding
unnecessary heating-up of rooms. The sensor used in PHOTASGARD
sensors was specifically adapted to the sensitivity of the human eye. Its greatest
sensitivity is in the range of 350 nm to 820 nm. Therefore with its special filter the
sensor is predestined for exposure measurement of daylight and ⁄ or for measuring
artificial light of high colour temperature (similar to sunlight).
