Monitor Arus dan Tegangan serta Fitur Pembatas Arus (over current) Sensor PZEM-004t ARDUNO

Monitor Arus dan Tegangan serta Fitur Pembatas Arus (over current) Sensor PZEM-004t ARDUNO

           Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat digunakan untuk monitor arus dan tegangan dan juga ada fitur pembatas arus sehingga kita bisa set pada berapa amper terjadi over current atau arus berlebih, jika terjadi arus berlebih maka akan otomatis off selama 2.5 detik. untuk lebih jelasnya berikut adalah komponen dan programnya.

a. Arduino Nano

b. Sensor PZEM-004t

c. SSR (Solid State Relay)

d. Program Arduino IDE
