GP2Y0A41SK0F Infrared Sensor Features
Sharp GP2Y0A41SK0F is an IR sensor that uses infrared wave to measure distance. The sensor’s output is analog, which can be easily read by microcontroller’s ADC converter. This sensor can be used in industry and especially in robotics. This sensor has an efficient range of 4cm to 30 cm.
Note
The sensor’s accuracy will decrease at distances over 40cm.

#include <Average.h>
// Reserve space for 10 entries in the average bucket.
// Change the type between < and > to change the entire way the library works.
Average<float> ave(10);
void setup() {
Serial.begin(9600);
}
void loop() {
int minat = 0;
int maxat = 0;
// Add a new random value to the bucket
ave.push((13 * pow(analogRead(A0)*0.0048828125, -1))+1.8);
Serial.println(ave.mean());
delay(100);
}
After running the code, you will see the following image in the serial output.
