An Arduino library for ESP32 development board that can measure distance from an analog Sharp IR sensor.

Currently supports:

• GP2Y0A21YK0F

Usage

• Adding the library to the sketch

#include <ESP32SharpIR.h>

• Creating an instance

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 );
sensorName.getRawDistance();
sensorName.getRawDistance( avoidBurstRead );

avoidBurstRead : can be true or false

• Apply a filter

sensorName.setFilterRate(float rate);

rate : a value from the range from 0.01 to 0.99. 0.01 equal to sampling 100 values and getting the average.
