Arduino-based sensors, such as ultrasonic or pressure sensors, enable cost-effective and versatile water depth measurements. These sensors interface with Arduino boards, allowing for real-time IoT ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

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 ...
