This Arduino library provides a convenient and easy-to-use interface for the PH4502C sensor, allowing you to effortlessly integrate it into your Arduino projects. The PH4502C sensor is a ...

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 ...

Arduino Nano; cheap pH meter probe with circuit; We used PH-4502C, which costs around 10 EUR, but it is unfortunately of a very low quality. However there are similar (compatible) probes on the market ...

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 ...

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 ...
