A simple project to measure the pH of a solution using an Arduino-based pH sensor and a web page that plots pH over time. Currently, the JavaScript code simulates random pH values as a demo. Once the ...

This repository contains two scripts written for the arduino. There are two operation modes: a single pH meter with two valves (one for adding acid and another for adding base) onto the same solution; ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...
