ch.aplu.android.ev3.HTInfraredSeeker

public class HTInfraredSeeker
extends Sensor

Class that represents a infrared seeker version 2 from HiTechnic. The device reports the reflection level of 5 infrared sensors (sensor id = 1..5) covering 60-degrees sectors. These levels correspond roughly to the distance of a reflecting object. Moreover the device reports the approximate direction of a reflecting object in nine 30-degrees sectors.

The underlying leJOS IRSeeker works for DC (constant) infrared sources.
