This is the sample code for Gravity: Analog pH Sensor / Meter Kit V2, SKU:SEN0161-V2
Product Link (https://www.dfrobot.com/product-1782.html)
SKU: SEN0161-V2
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, aquaculture, and environmental water testing.
To use this library, first download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo in the folder.
