Laser Emitter Module

The Laser Emitter Module is a small laser diode transmitter board made for Arduino and other microcontroller projects. It runs from 5 V and can be switched on and off from a digital pin, so you can use it as a pointer, as the light beam in a tripwire alarm with a light sensor, or as a simple optical signal in robotics and STEM experiments.

Laser Emitter Module Specifications

• Type: laser diode transmitter module
• Supply voltage: 5 V
• Control: on and off from a microcontroller digital pin
• Connection: header pins for Dupont jumper wires
• Works with: Arduino and other 5 V microcontroller boards

Laser Emitter Module Applications

• Laser tripwire and security alarms with an LDR or photodiode receiver
• Pointers and alignment guides
• Beam-break detection for counters and gates
• Robotics and STEM demonstrations

What's in the Box

• 1 × laser emitter module

Tip: Never look into the beam or point it at people, animals or shiny surfaces, as laser light can damage the eyes. For a beam-break alarm, aim the laser at a light sensor module and trigger the alarm when the sensor stops seeing the light.
