A much improved and accurate second generation of Panasonic’s Grid-EYE infrared array sensors is now available through TTI Europe. The new high gain types (AMG8833 and AMG8834) and low gain types (AMG8853 and AMG8854) of Grid-EYE 2nd Generation benefit from an improved NETD (Noise Equivalent Temperature Difference) of 0.16C at 10Hz and of 0.05C at 1Hz. For all models the detection distance has improved from 5m up to 7m. It is important to note that the second generation of 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. Panasonic is committed to improve the customer experience and provide much more application benefits with the improved MEMS technology.
Based on The company’s MEMS technology the 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 8x8 grid format that detect absolute surface temperature without any contact. Unlike conventional sensors, it uses a patented 60-degree silicon lens etched out of a silicon wafer, which is (with less than 0.3mm height) the smallest available lens in the market. The combination of these technologies allows for a sensor package size of only 11.6mm x 8mm x 4.3mm, which is around 70% smaller in size than competitors’ products.
Compared to single element thermopile sensors and pyroelectric sensors, the sensors not only detect moving and motionless people and objects, but does that in comparison to its predecessor models with higher precision and higher accuracy.
