All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, SensorConstants, SensorMode, SensorModes, SampleProvider

public class MindsensorsDistanceSensorV2
extends I2CSensor

Mindsensors DIST-Nx series of Optical Distance Sensors, Version 2
Mindsensors DIST Sensor measure the distance to an object in front of the sensor using IR light

Supported modes
Mode name	Description	unit(s)	Getter
Distance	Measures distance to an object in front of the sensor	Meter	getDistanceMode()
Voltage	Returns the output level of the sensors signal processing unit	Volt	getVoltageMode()

Sensor configuration
The sensor can be powered on and off using the powerOn and powerOff methods. It is useful to power off the sensor when not in use as it consumes a a fair bit of energy.
The sensor can be tuned for a particular Sharp optical distance sensor using the setModule method. See the top of the sensor for the Sharp module installed on the sensor.
The sensor supports hardware calibration but this in not supported by this interface.
