Alat Pendeteksi Arus Bocor (Deteksi Arus Bocor) ESP32 Sensor PZEM-004t dan IOT Thingspeak

Alat Pendeteksi Arus Bocor (Deteksi Arus Bocor) ESP32 Sensor PZEM-004t dan IOT Thingspeak

       Pada kesempatan kali ini saya akan menjelaskan mengenai bagimana cara membuat sebuah alat yang dapat digunakan untuk mendeteksi kebocoran arus, dikarenakan kebocoran arus sangat berbahaya dan merugikan, salah satunya yaitu dapat mengakibatkan biaya jadi besar dan jika arus bocornya lumayan besar maka akan mengakibatkan kesetrum jika terkena aliran arus tersebut, untuk itu perlu dipakaikan alat untuk memonitornya. untuk lebih jelasnya berikut adalah koding dan skemanya.
