IR array sensors boast improved accuracy

The IR array sensors integrate a more sensitive MEMS sensor chip, a digital ASIC (I²C interface), and a silicon lens in a small 11.6mm × 8mm × 4.3mm package — approximately 70 percent smaller than similar products.

The parts feature 64 thermopile elements in an 8×8 grid format that detect absolute surface temperature without any contact.

Unlike conventional sensors, Grid-EYE uses a patented 60-degree silicon lens etched out of a silicon wafer, which, at less than 0.3mm, is said to be the smallest available lens in the market.

The sensors provide thermal images by measuring actual temperature and temperature gradients, and they enable detection of multiple persons, identification of positions and direction of movement, almost independent of ambient light conditions without disturbing privacy as with conventional cameras.

The contactless sensors enable high-performance measurements for safety, household appliances, medical systems, lighting control, industrial controls, and many other applications.
