The sensor used in PHOTASGARD® light intensity sensors (photodiode with glass case) 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). The case of the
sensor is hermetically tight, the vision panel is protected by a glass plate.
In all KINASGARD® motion sensors and presence detectors, a high-end variant infrared sensor with enlarged angle of aperture is exclu-
sively used. Because of the patented lens system with 20 individual lenses, only very small dark areas are resulting, which even at a
distance of 10 m are only a few centimeters wide, safely detecting also small motions. The sensor recognizes changes in the infrared radia-
tion spectrum, so in heat radiation, resulting form the movement of persons or objects. Such movements generate a temporary change of
the temperature gradient in the field. Because of the always present body (heat) radiation, this sensor is excellently suitable for the detec-
tion of persons. The temperature difference between sensor and object must be > 5 K.
