The room light intensity sensor PHOTASGARD® RHKF with four switchable measuring ranges (four devices in one), measures the light intensity by means of a diffusor and is used to control luminaires, lighting systems, Venetian blinds and canvas blinds, to monitor lighting conditions at workplaces, in storage halls, workshops, corridors, in indoor areas, in industrial halls, in offices, as well as in residential and business facilities, for daylight-dependent constant light control, as light intensity or twilight sensor and to control sunshade equipment avoiding unnecessary heating-up of rooms. It therefore minimizes your variety of types and stock keeping while covering a greater range of universal applications. The sensor used 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 ideally suited to exposure measurement of daylight and ⁄ or for measuring artificial light of high colour temperature (similar to sunlight).
