Grid-EYE infrared array sensor

The second generation Grid-EYE infrared array sensor from Panasonic offers improved temperature resolution and increased measuring distance. The Grid-EYE sensor consists of 64 MEMS thermopile elements in an 8x8 pixel array on a single detector chip, and can measure actual temperature or temperature gradients. The presence of moving or stationary objects can be detected and Grid-EYE sensors can further detect the direction of moving people or objects, even detecting multiple objects moving in different directions.

The new high-gain types (AMG8833 and AMG8834) and low-gain types (AMG8853 and AMG8854) of Grid-EYE now benefit from an improved NETD (Noise Equivalent Temperature Difference) of  0.16°C at 10Hz and of 0.05°C at 1 Hz. For all Grid-EYE 2nd Generation models the detection distance has improved from 5m up to 7m. Importantly, the second generation of Grid-EYE sensors are fully compatible with the existing first generation designs.
