IR Thermophile Array Sensor – Grid-EYE
Introduction
Panasonic Grid-EYE is Infra-Red sensor comprised of 64 individual Thermopile elements arranged in an 8x8 matrix. The sensor comes in a compact surface mount package and can be very easily integrated into IoT applications. Infra-red signals are used to detect heat sources and measure temperature.
The integrated lens in Grid-EYE focuses the infra-red in the field of view (FoV) on to the sensor elements. This generates voltage differences between electrodes of individual Thermopile elements, which can be converted to temperature information.
Grid-EYE’s integrated ASIC performs some core functions to enable sensor’s performance–pixel readouts, analog amplification, analog to digital conversion, sensitivity correction, correction for temperature effects, and digital readout over I2C bus. Furthermore, Grid-EYE is available in high or low gain variants.
