This project demonstrates a simple water detection system using an Arduino board and a water sensor. The system uses an LED to indicate whether water is detected. The LED turns ON when no water is ...

Monitoring water levels in storage tanks or containers is crucial in various applications, such as agriculture, domestic water usage, and industrial processes. Traditional mechanical water level ...

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 sensor was ...
