The EmbeTronicX KY-008 650nm Laser Sensor Module 6mm 5V is a compact, red laser diode module designed to emit a focused 650 nm visible laser beam, making it ideal for targeting, alignment, positioning, and visual indication in robotics, automation, and embedded electronics projects. Its 6 mm laser head and standard 5V operation allow simple integration with common development boards and microcontrollers.

This module operates at 5V DC and can be driven from digital output pins (with proper current limiting or driver) of popular controllers such as Arduino, Raspberry Pi (via transistor driver), AVR, PIC, and ARM. The TTL-compatible input makes it easy to switch the laser on/off programmatically, enabling effects like laser pointers, range indication, object alignment aids, line guidance, and optical markers in robots or machines.

Engineers and hobbyists appreciate the KY-008 laser for its bright, coherent beam, which makes it suitable for visual feedback and precise pointing. It’s widely used in robotic navigation, DIY laser trip alarms, laser engraving guidance, optical experiments, and interactive art installations. The sturdy design with standard mounting pins supports prototyping and permanent installations alike.

Safety Note: This module produces a visible laser beam; avoid direct eye exposure, and always follow laser safety guidelines appropriate for the class of device you’re using.
