Simple & Safe Wiring to Arduino

Wiring to Arduino is effortless with four basic connections:

Tip: TX of the sensor goes to RX of Arduino, and RX to TX — simple and stable UART communication.

The module uses Class 2 laser level, ensuring safe operation for development and industrial testing scenarios without requiring additional protection.

Stable Green Laser + Optional Red Laser

Not every project runs in ideal indoor lighting. The 510–550nm green laser version offers:

• Higher visual brightness to the human eye

• Better detection on surfaces that are bright, white, or glossy

• Higher accuracy in outdoor light

If cost control is needed or performance requirements are moderate, the 610–690nm red laser model is also available.

You can choose the version according to your application environment.
