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 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 ...

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 ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...
