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 ...

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 ...

Testing Arduino pH Tester. We have tried this Arduino pH meter by dipping it into pure water and Lemon water, you can see the result below. Pure Water: Lemon Water: This is how we can build a 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 ...

When it comes to liquids, turbidity is an important term. Because it plays an important role in liquid dynamics and is also used to measure water quality.So in this tutorial, let's discuss what is ...

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 ...

Water is a novel resource that is abundant in nature. Over 70% of the Earth’s crust submerged in water bodies. Out of the total water available in Earth’s crust, 97% of the water which is saline in ...
