All about charging station and How to measure / monitoring current and voltage using internet

  

              Kali ini saya akan menjelaskan mengenai bagaimana cara membuat alat untuk memonitoring charging station, object yang akan dijadikan analisa adalah arus dan tegangan yang terdapat di charging station, fungsi charging station adalah untuk mengisi aki mobil listrik, seperti halnya SPBU tapi untuk mobil listrik. sehingga dibutuhkan sumber tegangan dan arus yang lumayan besar untuk sebuah charging station, jika tidak di pantau arus dan tegangannya, itu akan sangat berbahaya, pada contoh kali ini bisa dipantau via internet dan data bisa disimpan di database.
