Description

This 5V Laser Receiver Sensor Module output High Level is a sensor for Raspberry Pi and Arduino to receive the laser output and decode it digital data. At Input, the module Receive laser signal when output high level; Does not receive laser signal when output low level. On detecting a laser signal, output goes at a high level (5V) until the laser signal is there.

Features

  • Non-modulated laser beam for consistent signal detection
  • Compact and lightweight design
  • Easy to interface via analog or digital outputs
  • Wide operating voltage range
  • High sensitivity and fast response time

Interface GPIO / ADC (Arduino compatible)

Interfacing Laser Receiver Sensor Module to Arduino: Laser Sensor Security System

This project implements a laser-based security system using an Arduino Uno, consisting of a laser transmitter and receiver module. When the laser beam between the transmitter and receiver is interrupted, the system triggers an alarm through a buzzer and visual indication through an LED.

Project features:

  • Real-time laser beam interruption detection
  • Visual feedback through LED indicator
  • Audible alarm through buzzer
  • Serial monitor status reporting
  • Simple and reliable security implementation

Components Required

Pin Configuration

Component Arduino Pin
Laser Tx D2
Laser Rx D3
LED D12
Buzzer D5

Circuit Diagram of Laser Receiver Sensor Module to Arduino

Laser Sensor Module Non-Modulator Tube Laser Receiver Module circuit diagram

The circuit should be connected as shown in the schematic diagram above.

How It Works

  1. The laser transmitter continuously emits a laser beam to the receiver
  2. When the beam is uninterrupted:
    • LED is ON (system armed)
    • Buzzer is OFF
    • Serial monitor shows “Secure – Beam connected”
  3. When the beam is interrupted:
    • LED turns OFF
    • Buzzer activates
    • Serial monitor shows “ALERT! Beam interrupted!”

Installation

  1. Connect the components according to the circuit diagram
  2. Upload the provided Arduino code to your Arduino Uno
  3. Open Serial Monitor (baud rate: 9600)
  4. Power up the system

 

Serial Monitor Output

The system provides real-time status updates through the Serial Monitor:

Laser Security System Initializing...
System Armed and Ready!
Status: Secure - Beam connected
Status: ALERT! Beam interrupted

Usage

The system will start working immediately after powering up:

  • Green LED indicates system is armed and functioning
  • Buzzer will sound when the laser beam is interrupted
  • Monitor system status through Serial Monitor

Safety Notes

  • ⚠️ Do not point the laser beam at eyes
  • ⚠️ Ensure proper voltage levels for all components
  • ⚠️ Double-check connections before powering up
  • Keep laser path clear of reflective surfaces

Applications

  • Distance measurement
  • Obstacle avoidance robots
  • Industrial automation
  • Security and monitoring systems
Package includes:
1×Laser Sensor Module
