ESP32 SharpIR Library

ESP32 library to interface with SharpIR sensors

GitHub Badge

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

Currently supports:

  • GP2Y0A21YK0F
  • 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( avoidBurstRead );
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.
