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 ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. ... (such as PWM outputs for LED dimming or speaker ...

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 ...
