Este projeto demonstra um sistema simples de transmissão de dados baseado em laser usando microcontroladores Arduino. Ele permite a comunicação serial entre duas placas Arduino (Uno e Nano) usando um ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

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 ...

If you believe that a PM2.5/10 sensor can also detect O1, NO2, SO2 then go right ahead and market it as an “Air Quality” sensor. I look forward to the law suits.

Teledyne e2v has announced a family of CMOS image sensors for 3D laser triangulation – for use in applications such as distance measurement, profile measurement and high resolution physical inspection ...
