In this project we are going to make an Arduino pH Meter and learn how to measure the pH of a liquid solution using a gravity pH sensor and Arduino. A 16x2 LCD is used to show the pH value on the ...

Welcome to the pH Sensor Arduino Calibration repository! This repository contains resources and code for calibrating pH sensors using Arduino microcontrollers. pH sensors are widely used in various ...

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 ...

The pH of a solution can be determined using a pH meter or a pH indicator solution. The module utilises Hydrogen-ion activity also known as the “proton activity” for measuring pH of the liquid. This ...

These values are then shown on an LCD managed by the Arduino board. Calibration and verification of the device’s accuracy were conducted using buffer solutions with known pH values. Results: The ...
