Monitoring PH, Suhu, Turbidity, Jarak IOT Notif Telegram ESP32

Monitoring PH, Suhu, Turbidity, Jarak IOT Notif Telegram ESP32 

        Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang bisa memonitor PH, Suhu, Turbidity, Jarak via IOT Telegram, alat ini menggunakan ESP32 sehingga bagus untuk melakukan pengujian data secara online. untuk lebih jelasnya berikut adalah koding dan komponennya.
