Outdoor light intensity sensor PHOTASGARD® AHKF
The PHOTASGARD® AHKF light intensity or twilight sensor device supports six switchable measuring ranges (six devices in one) and measures the luminous intensity. It is used to control luminaries, lighting systems, Venetian and canvas blinds, etc., and to monitor lighting conditions at workplaces, in greenhouses, storage halls, workshops, corridors, outdoor areas, industrial halls and offices as well as in residential and business facilities. Further applications also include daylight-dependant constant light control, light intensity monitoring, twilight detection an sushade equipment control to avoid undesired heating-up of rooms. As a multi-functional device, it minimises your variety of types and stock keeping while covering a greater range of universal applications.
The sensor is specifically adapted to the sensitivity of the human eye. Its greatest sensitivity is in the range between 350 nm and 820 nm. Therefore, with its special filter, the sensor is ideally suited to exposure measurement of daylight and/or for measuring artificial light of high colour temperature (similar to sunlight).
