The ultrasonic sensor catches the object as it comes in its range (range decided in the code). So before the starting of the project , the code is to be written (on IDE) and uploaded in the Arduino ...

This project includes Arduino sketch code required to run an Arduino water sensor system. This system continuously monitors output from a SST Liquid Level Switch and notifies the configured phone ...

You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an off-the-shelf RGB sensor and wire it up to an Arduino.

Using the Arduino CapSense library, the sensor can detect the presence of water, signaling an alarm if the base needs refilling.

This paper presents an Arduino-based monitoring system that measures four physicochemical parameters of water: pH, temperature, turbidity, and electrical conductivity to identify possible water ...

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 ...
