SharpIR

An Arduino library that allows to acquire distance data from a Sharp analog distance sensor

Currently supported sensor models

• GP2Y0A41SK0F
• GP2Y0A21YK0F
• GP2Y0A02YK0F

Usage

• Adding the library to the sketch

#include <SharpIR.h>

• Creating an istance

SharpIR sensorName(sensorModel, sensorPin);

sensorName	: the name of the object   
sensorModel	: the model code of the sensor (e.g. GP2YA41SK0F)  
sensorPin	: the analog pin where the sensor Vout pin is attached  

• Acquiring data

sensorName.getDistance();
sensorName.getDistance( avoidBurstRead );

avoidBurstRead	: can be true or false

The above method returns an uint8_t type value that is the distance in centimeters from the sensor and the object in front of it.
By default burst reads are avoided but this causes a delay of 20ms on every call. In order to speed up the sketch is possible to allow bust reads by setting the parameter avoidBurstRead to false, in this way:

sensorName.getDistance( false );
