Monitor Gas dan Asap FUZZY LOGIC MAMDANI Arduino

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang bisa digunakan untuk monitor gas dan asap dengan menggunakan metode fuzzy logic mamdani, alat ini menggunakan 4 buah sensor sebagi inputnya dan outputnya menggunakan relay. untuk lebih jelasnya berikut adalah komponen dan kodingnya.

a. Arduino Mega

b. Sensor Gas MQ2 dan MQ135

c. Program Arduino IDE
