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 ...

Libelium's sensors connect to the Intel Galileo development board, allowing makers and developers to use the new development platform for Internet of Things projects, with Arduino and Raspberry Pi.

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 ...
