An Arduino Uno pH sensor measures the acidity or alkalinity of a solution by detecting hydrogen ion concentration. It's commonly used in hydroponics, aquariums, and environmental monitoring for pH ...

Then connect one wire of Solenoid valve with the battery's +ve terminal, it's other wire to the relay and battery's -ve terminal to the relay. Connect the mobile phone to the same network with which ...

If you want to know the acidity (or alkalinity) level of your pool or aquarium water, you need a pH meter. In this article, you'll find a simple but effective solution based on off-the-shelf ...

The ADIY pH sensor module can precisely measure the potential of hydrogen (pH) of any liquid. Rajguru Electronics has released the ADIY pH sensor module, a sensor for measuring the potential of ...

There’s an old saying that the cobbler’s children have no shoes. Sometimes we feel that way because we stay busy designing things for other people or for demos that we don’t have time to just build ...

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 ...
