Laser Sensor

A red laser diode mounted on a small breakout board with the current-limiting circuitry already fitted, so it connects to an Arduino pin and ground directly. Switch it on and off in code to build beam-break detectors, tripwires, object counters and alignment tools. Use it with a matching laser receiver module positioned opposite. Observe standard laser safety and never aim it toward eyes. Ready-wired breakout, no external components needed; Switched directly from an Arduino digital pin; Bright, tightly focused red beam; Designed to pair with laser receiver modules
