Interfacing TDS sensor with Arduino program

 hi friends in this section we learn about the Interfacing TDS sensor with Arduino . this TDS sensor is help to measure the total dissolved solids in water.

Tutorial video :

Interfacing TDS sensor with Arduino program :

#include <EEPROM.h>

#include "GravityTDS.h"

 

#define TdsSensorPin A1

GravityTDS gravityTds;

 

float temperature = 13,tdsValue = 0;

 

void setup()

{

    Serial.begin(9600);

    gravityTds.setPin(TdsSensorPin);

    gravityTds.setAref(5.0);  //reference voltage on ADC, default 5.0V on Arduino UNO

    gravityTds.setAdcRange(1024);  //1024 for 10bit ADC;4096 for 12bit ADC

    gravityTds.begin();  //initialization

}

 

void loop()

{

    //temperature = readTemperature();  //add your temperature sensor and read it

    gravityTds.setTemperature(temperature);  // set the temperature and execute temperature compensation

    gravityTds.update();  //sample and calculate

    tdsValue = gravityTds.getTdsValue();  // then get the value

    Serial.print(tdsValue,0);

    Serial.println("ppm");

    delay(1000);

}

if you have any doubts about this project comment on my YouTube channel i will respond as well as possible .
