In this article, we present a pH meter that can accurately measure the pH value of a solution. We use a dedicated sensor, the Arduino UNO R4 Minima board.

This Arduino project reads pH values from a pH sensor and sends the data to the ThingSpeak IoT platform via Wi-Fi. The project utilizes an analog pH sensor connected to analog pin A0 and communicates ...

This project demonstrates how to use a capacitive touch sensor module with an Arduino Uno. The touch sensor detects touch or proximity, triggering an action in response to the input. Connect the ...

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 ...
