Laser Light Receiver for 140 to 205KHz

Description

What it is

The Laser Light Receiver for 140 to 205KHz is a device sensitive to specific laser frequencies, ideal for projects requiring laser beam detection. This component can be used in various applications such as interactive or security systems.

Features

• Compatible Frequencies: 140 to 205KHz
• Ideally suited for projects with Arduino and other microcontrollers

What it is for

The light receiver is used to create interactive systems that detect the presence of the laser beam. It is perfect for applications such as security control, where a beam interruption can trigger a specific reaction (for example, turning on or off a light bulb). Additionally, it is compatible with Arduino and other microcontrollers.

Tutorial: How to use the Laser Light Receiver

The laser light receiver allows detecting the presence and intensity of the laser beam. Ideal for interactive or security projects.

What you need

• Arduino
