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 ...

Here we are interfacing pH sensor and Arduino to make pH meter which can measure the pH values of any liquids and display the pH values on LCD display. You can also learn how to calibrate the Ph ...

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 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 ...

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 ...

We connected $\\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The sensor was ...
