This study covers the design and testing of a low-cost, “build-it-yourself”, instream water depth sensor providing an assessment of its potential in future hydrological monitoring projects. The ...

Displays sensor readings on the OLED screen using I2C communication. Hardware Requirements Microcontrollers: 2 x ESP32 Sensors: TDS Meter pH Sensor Temperature Sensor Water Flow Sensor Water Pressure ...

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 ...
