Second generation Grid-EYE infrared array sensors are ‘much improved’
The much improved and accurate second generation of its Grid-EYE infrared array sensors has been released by Panasonic Automotive & Industrial Systems Europe.
The new high gain types (AMG8833 and AMG8834) and low gain types (AMG8853 and AMG8854) of Grid-EYE 2nd Generation 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. The second generation of Grid-EYE sensors is fully compatible with the existing first generation designs. This means that the engineers can now get improved and accurate results when they use the sensor in their applications.
Based on the company’s MEMS (Micro Electro Mechanical Systems) technology the array sensors combine a more sensitive MEMS sensor chip, a digital ASIC (I2C interface) and a silicon lens in the same small package. 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° silicon lens etched out of a silicon wafer, which is (with less than 0.3mm height) the smallest available lens in the market, says the company. The combination of these technologies allows for a sensor package size of 11.6mm x 8mm x 4.3mm.
Compared with single element thermopile sensors and pyroelectric sensors, the Grid-EYE 2nd Generation can not only detect moving and motionless people and objects but does that in comparison to its predecessor models with higher precision and higher accuracy.
