Panasonic launches first ever surface mount thermopile array sensor identifies movement, direction and multiple objects

9 FEBRUARY 2015

Panasonic Automotive & Industrial Systems has launched the first–ever surface mount thermopile array sensor. Grid-EYE features 64 thermopile elements in an 8×8

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 or additional energy saving capabilities in stand-by mode, offering a high degree of flexibility.
Measuring 11.6 × 4.3 × 8.0mm, Grid-EYE arrays have an operating voltage of 3.3V or 5V and a typical current consumption of 4.5mA (normal mode); 0.8mA (stand-by mode); and 0.2mA (sleep mode). Object temperature range is 0-80°C for the high gain amplification version and -20-100°C with low gain.
Overall Temperature accuracy is ± 2.5°C with an NETD (Noise Equivalent Temperature Difference) of ± 0.5°C, depending on P/N.
Compared to single element thermopile sensors and pyro-electric detectors, Grid-EYE sensors offers extended possibilities for detecting persons and objects, enabling advanced Applications.
Applications include: Digital Signage; Security; Lighting Control; Kiosks/ATMs; Medical Imaging; Automatic Doors, People counting.
