Laser Photoelectric Switch (SKU:FIT0319)

Introduction

The laser photoelectric switch is a photoelectric switch that is composed of emitter and receptor.The emitter consists of a laser diode,and the laser has the characteristics of high precision, good orientation etc.The receptor consists of a photoelectric element.When receiving the laser pulse, the built-in light conducting.The emitter and receptor can assemble a detector. It can be directly compatible with Arduino to develop related products .Of course,it is also very suitable for photoelectric counting, security, ultra-high vehicle overrun detection etc.

Class 3R are usually up to 5 mW and involve a small risk of eye damage within the time of the blink reflex. Staring into such a beam for several seconds is likely to cause damage to a spot on the retina.

Connection Diagram

Laser Photoelectric Switch

The output pin of the laser photoelectric switch is connected to pin 10 of the Arduino board.The LED on 13 pin will reflect the state of the output pin.Try to block the laser and watch the effect. The Receptor will output high level when it detects laser signal.
