Acxico 2-Set Laser Sensor Module For Arduino – KY-008 Transmitter + Receiver, 5V, 650nm, Non-Modulated

About This Product

If you’re tinkering with Arduino or AVR projects and need a laser tripwire or detection setup, this two-pack from Acxico has you covered.

You get two KY-008 laser transmitter modules and two laser receiver modules—so you can build multiple sensors or have spares on hand.
Both run on 5V, and the transmitter puts out a 650nm red laser beam.

The receiver is a non-modulated type, which means it’s simple and straightforward but works best in darker environments—sunlight or bright indoor lights can interfere, so plan your setup accordingly.
The receiver outputs high when it sees the laser, low when it doesn’t, so it’s easy to trigger alarms, count objects, or detect movement.
Modules are small—about 15x24mm for the transmitter and 15x22mm for the receiver—so they fit into tight spots.

Great for robotics, security demos, or just learning about sensors.

Just keep in mind the size and lighting conditions before you buy.

Overall, a cheap and fun way to add laser sensing to your next project.

5V operating voltage – works with standard Arduino and AVR boards.

650nm wavelength – visible red laser for easy alignment.
Non-modulated receiver – simple high/low output; best used in low-light conditions.

Compact size – transmitter 15x24mm, receiver 15x22mm.

Set includes 2 transmitters + 2 receivers – enough for multiple projects.
