ELCB Arduino Sensor PZEM-004t IOT Blynk

ELCB Arduino Sensor PZEM-004t IOT Blynk 

 

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah ELCB dengan arduino dan iot blynk. alat ini menggunakan 2 buah sensor arus tegangan PZEM-004t. dan juga alat ini menggunakan wemos D1 mini esp8266. untuk lebih jelasnya berikut kodingnya.
