Infrared array sensors provide thermal images by actual temperature and gradients

Stocked by Mouser, Panasonic Grid-EYE (Gen 2) infrared array sensors are surface mountable and feature 64 thermopile elements in an 8x8 grid format that detect absolute temperatures by infrared radiation. The sensor is able to provide thermal images by measuring actual temperature and temperature gradients. It enables 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 built-in silicon lens provides a viewing angle of 60 degrees. Measurement values are viewable through an I²C interface in 1 or 10 frames per second. The interrupt signal output delivers a quick response to time-critical events for a high degree of flexibility. Compared to Gen 1, the Gen 2 the device offers higher accuracy, enhanced resolution and longer detection distance, for true next-generation performance. Typical applications include safety, household, medical systems, lighting control and industrial temperature measurement.
