Monitor PH dan Turbidity TDS Serta Water Level JSN-SR04 IOT BLYNK 2.0 ADS1115 Nodemcu ESP8266

Monitor PH dan Turbidity TDS Serta Water Level JSN-SR04 IOT BLYNK 2.0 ADS1115 Nodemcu ESP8266

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor PH dan turbidity serta water level atau ketinggia air secara realtime online dengan server IOT Blynk 2.0 sehingga bisa dimonitor secara jarak jauh. untuk lebih jelasnya berkut adalah koding dan skemanya.
