The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. pH is a measure of the basicity or acidity of a solution ...

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 ...

Connect Po to Analog input A0 on Arduino, and G to Arduino GND. Run the given Arduino sketch below, and open the Serial Monitor of Arduino IDE to observe the reading, slowly adjust the potentiometer ...
