GR2173X5 5V Laser Receiver Sensor Detection Module – non-modulated laser detector on a compact 1.5×1.9 cm PCB. Outputs HIGH when laser is detected, LOW when not. Ideal for Arduino projects in controlled light environments.

 

The GR2173X5 5V Laser Receiver Sensor Detection Module (OEM) is a compact, non-modulated laser detection module designed to work alongside a laser emitter such as the KY-008. Operating at 5V, it outputs a digital HIGH signal when a laser beam is received and a digital LOW when no laser is present — making it straightforward to integrate into any microcontroller project that needs beam-break or presence detection logic.

Key Features

  • Non-Modulated Receiver: Detects continuous laser beams directly → simple, no-library digital output
  • 5V Operating Voltage: Plug-and-play with Arduino UNO, Nano, Mega and other 5V platforms → no level-shifting required
  • Digital Output Logic: HIGH on laser detection, LOW on no signal → easy to read with digitalRead()
  • Compact PCB: 1.5 × 1.9 cm footprint → fits tight spaces and breadboards

Compatibility

  • Arduino UNO / Nano / Mega: Direct connection — 5V supply matches perfectly, digital output readable on any GPIO pin.
  • Note for 3.3V platforms (ESP32, Raspberry Pi): Module operates at 5V; a logic level shifter is recommended on the signal line when interfacing with 3.3V GPIO pins.

Typical Applications

  • Laser beam-break detection: Trigger an alarm or counter when an object interrupts the beam between a KY-008 laser and this receiver.
  • Object presence sensing: Detect whether a part or product is in position on an assembly or conveyor system.
  • DIY security/alarm systems: Build a simple perimeter trip-wire with a laser emitter and this module in a dark indoor environment.
  • Educational robotics: Demonstrate digital sensor logic and interrupt-driven programming for Arduino students.
  • Line-of-sight communication experiments: Explore simple optical signalling in controlled, light-free lab setups.

FAQ

Q: Can I use this module outdoors or under bright indoor lighting?
A: No. The non-modulated receiver cannot filter ambient light. It is designed strictly for dark or light-controlled indoor environments — sunlight or strong artificial light will cause false triggers.

Q: Which laser emitter is compatible with this module?
A: Any continuous-wave (non-modulated) 5V laser emitter pointing at the receiver will work, such as the KY-008 5V Laser Head Sensor Module.

⚠ Warning: Always use in dark or light-controlled indoor environments. Ambient light, sunlight, or bright fixtures will interfere with detection and may cause unreliable readings. Never point laser beams at eyes.
