Pakan Ikan Monitor PH Turbidity Amoniak Suhu dan Monitor Water Level IOT Blynk 2.0
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang bisa mengukur PH Turbidity Suhu dan water level via IOT Blynk. alat ini juga terdapat RTC sebagai pewaktu, jadi ketika waktu sesuai dengan setingan maka pelontar berupa servo akan aktif. berikut adalah kodingdan skemanya.
