Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

A laser security system is a type of alarm system that uses beams of light to detect intruders.The system consists of a laser source, a receiver and a controller. The laser source emits a beam of ...

This project is a Laser Morse Code Encoder and Decoder system designed to facilitate secure and efficient communication using light signals. Leveraging the simplicity and reliability of Morse code, ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
