Compatibility
This module works with any microcontroller that has a digital input, including Arduino Uno, Nano, ESP32, and Raspberry Pi. It supports 3.3V and 5V logic levels. A common pairing is the KY-008 laser transmitter module for a complete optical setup.
Wiring Notes
Connect VCC to 5V, GND to GND, and OUT to a digital pin. If the signal is unstable, add a 10kĪ© pull-up resistor between OUT and VCC. Shield the sensor from ambient light for reliable operation.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the module operates at 5V and provides a digital output that can be read by any Arduino digital pin. Simply connect VCC to 5V, GND to GND, and OUT to a digital input.
Can it detect any laser color?
It is optimized for 650nm red lasers, which are the most common. It may work with other visible wavelengths, but sensitivity is highest in the red spectrum.
How far can it detect a laser?
With a standard 5mW red laser pointer, the detection range is up to 10 meters in a straight line. For longer distances, use a higher power laser.
