 # Omron-Arduino
-Arduino code to get data out of the incredible 4x4 IR OMRON MEMS sensor.
-Omron D6T is a MEMS IR sensor that has the distinct advantage of sensing human presence even if the individual is stationary. The sensor array also allow sensing of movement direction of the person.
-
-Example Image from the Omron D6T 4x4 array:
-
-![alt tag](ExampleImage.png?raw=true "Image Title")
-
-In this image the brighter pixels correspond to a warmer body. Note that the OMRON D6T-44L returns data in a 4x4 format. To view the result in a large image like this, I used Matlab to resize to a much larger image and mapped the image intensities with some sensible intensity transforms (power transform).
+Arduino code to read Omron D6T IR sensor.
