Key Features of Laser Receiver Module
- Pairs seamlessly with standard 650nm laser transmitter modules for reliable beam-break detection
- Onboard LM393 comparator delivers clean, noise-free digital output signals
- Adjustable sensitivity potentiometer lets you fine-tune detection threshold for varying distances and ambient light
- Dual onboard LEDs provide instant visual feedback for power status and laser detection
- Simple 3-pin interface connects directly to any microcontroller without additional circuitry
Perfect For
- Laser Tripwire Security System: Pair with a laser transmitter to create an invisible beam across doorways or perimeters. When the beam is broken by an intruder, trigger buzzers, lights, or send alerts to your phone via Wi-Fi.
- Object Counting System: Set up a laser beam across a conveyor belt or pathway. Each time an object passes through and breaks the beam, the receiver detects the interruption and increments a counter on an LCD display.
- Laser-Based Communication: Transmit simple data by modulating a laser beam on and off. The receiver decodes the signal, enabling line-of-sight optical communication experiments over short to medium distances.
- Smart Safe or Vault Lock: Build a laser grid inside a box or safe. If anyone reaches inside and breaks a beam, an alarm sounds and a servo locks the lid shut automatically.
- Speed Measurement Device: Use two laser receiver modules spaced a known distance apart. Measure the time difference between beam breaks to calculate the speed of a passing object, such as a toy car or ball.
- Interactive Laser Maze Game: Create a physical maze of laser beams using mirrors and multiple transmitter-receiver pairs. Players must navigate through without breaking any beams, with a buzzer signaling any contact.
- Robotics Line-of-Sight Sensor: Mount the receiver on a robot and use a stationary laser as a beacon for navigation or positioning reference in robotics competitions.
- Automated Lighting Control: Use the laser beam-break principle to detect when someone enters or exits a room and automatically toggle lights on or off using a relay module.
How It Works
The Laser Receiver Module uses a sensitive photodetector element tuned to detect laser light, particularly in the 650nm red wavelength range. When a laser beam strikes the sensor, the onboard LM393 comparator processes the analog signal and outputs a clean digital HIGH or LOW signal. When the laser beam is interrupted or blocked, the output state changes, allowing your microcontroller to trigger alarms, count objects, or initiate any programmed response. The onboard potentiometer lets you adjust the detection threshold to accommodate different laser intensities and ambient lighting conditions.
Wiring Guide
| Module Pin | Microcontroller Connection |
| VCC | 5V Power Supply |
| GND | Ground (GND) |
| OUT (Signal) | Any Digital Input Pin (e.g., D2 on Arduino) |
Setup Tip: Position the laser transmitter module directly facing the receiver sensor at your desired detection distance. Adjust the onboard potentiometer using a small screwdriver until the signal detection LED responds reliably to the laser beam. Start with short distances and gradually increase while fine-tuning sensitivity.
