Monitor Arus dan Tegangan 3 Fasa IOT BLYNK GRAFIK REALTIME

Monitor Arus dan Tegangan 3 Fasa IOT BLYNK GRAFIK REALTIME

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang digunakan untuk monitor arus dan tegangan 3 fasa dengan menggunakan IOT Blynk sehingga bisa dilakukan monitor secara jarak jauh menggunakan web atau handphone. untuk lebih jelasnya berikut adalah koding dan komponennya.

PZEM004Tv30 pzem3(A10, A11);

int voltage1, voltage2, voltage3;

float arusR, arusS, arusT;

void setup() {

  lcd.begin();   

  lcd.noCursor();

  lcd.clear();

  Serial.begin(9600);    

}

void loop() {

  

voltage1 = pzem1.voltage();

voltage2 = pzem2.voltage();

voltage3 = pzem3.voltage();

arusR = pzem1.current();

arusS = pzem2.current();

arusT = pzem3.current();

lcd.setCursor(0, 0);

lcd.print(voltage1);

lcd.print("/");

lcd.print(voltage2);

lcd.print("/");

lcd.print(voltage3);

lcd.print(" ");

lcd.setCursor(0, 1);

lcd.print(arusR);

lcd.print("/");

lcd.print(arusS);

lcd.print("/");

lcd.print(arusT);

lcd.print(" ");

Serial.print("*");

Serial.print(arusR * 100.0);

Serial.print(",");

Serial.print(arusS * 100.0);

Serial.print(",");

Serial.print(arusT * 100.0);

Serial.println("#");  

delay(200);
