First post

Hi everybody.

I am really happy to announce the launch this project: a pH meter using a Arduino/Freeduino board.


Construct a pH meter using an Arduino/Freeduino board to read pH with a pH glass electrode. It is not a high resolution scientific instrument. This project aims to be simple, using resources from the Arduino, commons and cheap electronic components. The pHduino could be operate connected to a computer by a USB cable or in a stand alone mode using a display and powered by a power supply or a battery. Important: It is fundamental connect a pH sensor (e.g. pH glass electrode) to the pHduino.


First, the pHduino aims to be useful in a chemistry laboratory to read pH of solutions. It can be used in a didactic chemistry laboratory or in analytical applications like potentiometric titration. Other applications could be the monitoring the pH of an aqueous solution from aquariums, reservoirs, lakes, rivers, swimming pools, rain, industrial processes, etc.

This is my contribution for the chemistry, open source and open hardware communities.

  1. hey nice information for us,thanks for sharing this information.A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid.
