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 ...

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 ...

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...

This study introduces a pH meter design utilizing the Arduino platform, a cost-effective and user-friendly open-source electronic platform.Objective: To develop and test an Arduino-powered pH meter ...

When it comes to liquids, turbidity is an important term. It plays an important role in liquid dynamics and is also used to measure water quality. Monitoring the quality of water is becoming ...

This present paper introduces an innovative approach to automatically monitor and control acidity or alkalinity in irrigation water. The system effectively calculated the amount of acidic or alkaline ...
