Grid-EYE Sensor array

Grid-EYE features 64 thermopile elements in an8x8 grid format that detect absolute temperatures by infrared radiation.

Grid-EYE is able to measure actual temperature and temperature gradients, providing thermal images. It is easily possible to detect multiple persons, identify positions and direction of movement, almost independent of ambient light conditions without disturbing privacy as with conventional cameras. Cost-effective and compact solutions for contactless temperature measurement across the entire specified area can be and with very accurate results. The built-in silicon lens provides a viewing angle of 60°.The measurement values can be read out via I²C interface in 1 or 10 frames per second. The interrupt signal output delivers a quick response to time-critical events, offering a high degree of flexibility. Compared to single element thermopile sensors and pyro-electric detectors, Grid-EYE sensors offers extended possibilities for detecting persons and objects, enabling advanced Applications.
