interfacing ph sensor with arduino

You will need to connect the pH sensor to the Arduino board and configure the pins accordingly. Refer to the documentation of your pH sensor for more information on how to do this.

Note that this is just a sample code and may need to be modified depending on your specific requirements.

// Libraries

#include <LiquidCrystal.h>     // Liquid Crystal library for display

#include <Wire.h>              // I2C protocol library

#include <SparkFun_PH_EC_Salinity.h> // pH sensor library

// Objects

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); // LCD pins

PH_EC_Salinity ph;           // pH sensor object

// Variables

float pHValue = 0.0;         // pH value variable

void setup() {

  // Initialize LCD

  lcd.begin(16, 2);

  lcd.clear();

  lcd.setCursor(0,0);

  lcd.print("pH Sensor Test");

  

  // Initialize pH sensor

  ph.begin();

}

void loop() {

  // Read pH value

  pHValue = ph.getPH();

  

  // Display pH value on LCD

  lcd.setCursor(0,1);

  lcd.print("pH: ");

  lcd.print(pHValue, 2);

  

  // Wait for 1 second

  delay(1000);

}

To use this code, you will need to install the following libraries:
