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 ...

pH Sensor with Arduino and Display System The pH Sensor with Arduino and Display System is a compact and efficient solution for measuring and displaying the pH levels of soil or water. By connecting ...

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 ...

As mentioned earlier, this circuit takes its power directly from the Arduino UNO R4 board’s 5 V and GND pins. The pH-detection module’s pin P0 was connected to the Arduino board’s analog pin A0. This ...

Background: Accurate pH measurement is vital in diverse settings such as water quality assessment, food production, and laboratory procedures. This study introduces a pH meter design utilizing the ...

Abstract: 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 ...
