Monitor Suhu dan PH serta Turbidity Kolam Ikan dan juga Fitur Pakan Otomatis via BLYNK 2.0 ESP32

Monitor Suhu dan PH serta Turbidity Kolam Ikan dan juga Fitur Pakan Otomatis via BLYNK 2.0 ESP32 

       Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor PH dan suhu air serta turbidity air pada kolam ikan, alat ini juga terdapat fitur yaitu jika pada jam yang telah ditentukan maka motor atau relay akan membuka pakan sehingga akan memberikan pakan otomatis di jam tertentu. untuk lebih jelasnya berikut adalah komponen dan kodingnya.
