Ciara's changes

The original library won't compile on the Arduino Uno R4 WiFi, with the compiler citing the absence of the function "strupr". All I have done is write a very basic "string to uppercase" function and conditionally include it if one is not found.

Installation

Go to the Arduino libraries folder and clone this repo. Make sure you don't have the original library since they have the same names and will probably conflict.

Summary

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.

Installation

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.
Depends library: https://github.com/DFRobot/DFRobot_EC

Methods

  /**
   * @fn calibration
   * @brief Calibrate the calibration data
   *
   * @param voltage     : Voltage value
   * @param temperature : Ambient temperature
   * @param cmd         : enterph -> enter the PH calibration mode
   * @n                   calph   -> calibrate with the standard buffer solution, two buffer solutions(4.0 and 7.0) will be automaticlly recognized
   * @n                   exitph  -> save the calibrated parameters and exit from PH calibration mode
