Gen 2 Vex IQ Optical Sensor

The IQ Optical Sensor is a combination of ambient light, color, proximity and gesture sensor.  Color information is available as RGB, hue and saturation or grayscale.  Color detection works best when the object is closer than 100mm.  

The proximity sensor measures reflected light intensity, and as such, the values will change with ambient light and object reflectivity.  The Optical Sensor has a white LED to assist color detection in  low light conditions.

The gesture sensor can detect one of four possible gestures, an object (hand or otherwise) moving up, down, left or right over the sensor.  

Note: The Gen 2 Vex IQ Optical Sensor replaces all the functionality of the VEX IQ Color Sensor (228-3012)
