Introduction

 
This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. 
By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes 
between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet 
dispensing, general object detection, etc. Gap width = 10mm

 

Specification

Supply Voltage: 3.3V to 5V

Interface: Digital

 
Example code 

photo interrupter module
 
int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the photo interrupter sensor interface
int val ;// define numeric variables val
void setup ()
{
  pinMode (Led, OUTPUT) ;// define LED as output interface
  pinMode (buttonpin, INPUT) ;// define the photo interrupter sensor output interface   
}
void loop ()
{
  val = digitalRead (buttonpin) ;// digital interface will be assigned a value of 3 to read val
  if (val == HIGH) // When the light sensor detects a signal is interrupted, LED flashes
  {
    digitalWrite (Led, HIGH);
  }
  else
  {
    digitalWrite (Led, LOW);
  }

}
