MONITOR PH - TDS - SUHU - JARAK BLYNK ESP8266

MONITOR PH - TDS - SUHU - JARAK BLYNK ESP8266 

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapa memonitor PH, TDS, Suhu, Jarak menggunakan Blynk secara realtime. alat ini menggunakan relay sebagi kedali dari pompanya dan juga menggunakan Nodemcu ESP8266 sebagai microcontrollernya. untuk lebih jelasnya berikut adalah koding dan skemanya.
