Monitor DAYA (Arus Tegangan) AC dan DC Thingspeak + Monitor Android

Monitor DAYA (Arus Tegangan) AC dan DC Thingspeak + Monitor Android

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur 6 buah parameter yaitu tegangan AC, arus AC, Daya AC, Tegangan DC, Arus DC dan Daya DC. data tersebut dikirimkan ke server thingspeak lalu akan dibaca oleh aplikasi android. untuk lebih jelasnya berikut adalah koding dan komponennya.

 

a. Nodemcu ESP8266

b. Sensor INA219

c. Sensor PZEM-004T

d. Sensor DC Voltage

 

e. Aplikasi Android

Note: pada bagian LINK tuliskan seperti berikut ini dan sesuai dengan ID thingspeak dan ID Write apikey pada website / akun thingspeak Anda. yang berwarna merah adalah ID akun thingspeak dan warna biru adalah ID Write apikey.
