Keyestudio EASY plug Photo Interrupter Module

Introduction

This is a high performance EASY Plug photo interrupter module.
The upright part on the module combines an infrared light emitting diode and shielded infrared detector.
By emitting a beam of infrared light from one end to another end, the sensor can detect an object when it passes through the beam.
Useful for many applications such as optical limit switches, pellet dispensing, general object detection, etc.
Note: this module needs to be used together with EASY plug control board.

Specification

• Connector: Easy plug
• Supply Voltage: 3.3V to 5V
• Interface: Digital

Technical Details

• Dimensions: 38mm*20mm*18mm
• Weight: 4.8g

Connect It Up

Connect the EASY Plug photo interrupter module to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload.

// photo interrupter module
 
int Led = 13 ;// define LED Interface
int buttonpin = 6; // 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);
  }
}

What You Should See

Done uploading the code, powered on, if pick up a piece of paper in the groove part on the module, you should see the indicator LED on the control board is turned on. If move the paper, the LED is turned off.
