Monitoring Tegangan Arus Daya Freq 2 Buah PZEM-004t dan Kendali Relay via IOT Blynk

Monitoring Tegangan Arus Daya Freq 2 Buah PZEM-004t dan Kendali Relay via IOT Blynk 2.0

       Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur arus dan tegangan menggunakan sensor PZEM-004t dan juga bisa kendali relay via IOT Blynk untuk lebih jelasnya berikut adalah koding dan skemanya.
