INTRODUCTION
WHAT IS GRIDEYE? Overview GridEYE is an 8x8 (64) pixel infrared array sensor. It uses an array of thermopile to measure actual temperature as well as temperature gradients It comes with a built-in lens with 60 viewing angle. It is a high precision compact SMD design using MEMS technology. Features Based on thermopile technology, GridEYE can detect the direction of moving people and objects up, down, left, right and diagonally. Its coordinated array of sensing elements can even detect multiple people or objects moving in different directions. At close proximity, Grid-EYE is even capable of detecting hand movements for simple gesture control. October 6, 2015 5
HOW DOES IT WORK? Temperature measurement New sensing options compared to conventional sensor device Multiple elements measure the temperature of each area Sensor Human body wavelength 10um range Thermal image Infrared Array Sensor 8x8=64pixels October 6, 2015 6
GRIDEYE ADVANTAGE/COMPARISON Moving Motionless Movement Temperature object object direction measuring Pyroelectric Possible Impossible Impossible Impossible Thermopile (Single element) Possible Impossible Impossible Impossible Grid-EYE Possible Possible Possible Possible A lot more functionality as compared to Pyro-electric and Thermopile. Above extended features of GridEYE make it possible to be used in a wide variety of applications. GridEYE is the latest technology of sensor products available in smallest size in market today.
