Monitor TDS / NTU / Turbidity dan PH ONLINE Blynk FUZZY LOGIC CONTROL MAMDANI
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang menggunakan metode fuzzy logic mamdani untuk input sensot PH dan turbidity. alat ini menggunakan lcd sebagai interface dan juga bisa dimonitor melalui aplikasi blynk. untuk lebih jelasnya berikut adalah koding dan komponennya.
a. Arduino Mega
b. Nodemcu esp8266
c. Sensor PH
d. Sensor Turbidity
e. Membership Function
f. Fuzzy Rule
g. Defuzzifikasi
h. Program Arduino IDE
