Analog pH meter V2 is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. DFRobot ph sensor is commonly used in various applications such as aquaponics, ...

This Arduino code reads the output of a pH sensor connected to analog input A0 and calculates the corresponding pH value. It then prints the pH value and classification (Acidic, Neutral, or Alkali) to ...

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 ...
