Grid-EYE is able to measure actual temperature and temperature gradients, providing thermal images. The device can detect multiple persons, identify 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°. 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 are said to offer extended possibilities for detecting persons and objects, enabling advanced applications such as digital signage; security; lighting control and building automation, or people counting.
