ch.aplu.ev3.HTEopdSensor

public class HTEopdSensor
extends Sensor

Class that represents an Electro-Optical Proximity Detector (HiTechnic EDPD). The sensor measures distance uniformly colored objects in range of about 15 cm. It is much less effected by ambient light than a standard color or light sensor.

Constructor Detail

HTEopdSensor

public HTEopdSensor(SensorPort port)

Creates a sensor instance connected to the given port in long distance mode. The long distance mode is the standard mode using high sensitivity.

Parameters:

port - the port where the sensor is plugged-in

HTEopdSensor

public HTEopdSensor()

Creates a sensor instance connected to the given port in long distance mode. The long distance mode is the standard mode using high sensitivity.

Method Detail

getLejosSensor

public lejos.hardware.sensor.HiTechnicEOPD getLejosSensor()

Returns the reference of the the underlying lejos.hardware.sensor.HiTechnicEOPD.

Returns:

the reference of the lejos.hardware.sensor.EV3ColorSensor

getDistance

public int getDistance()

Polls the sensor.

Returns:

the current value the sensor reported in arbitrary units from 0..999 (999 if the sensor does not detect a target)
