Monitoring of Smoke in the Room with the Fuzzy Method Based on The Internet of Things (IoT)

Until now, the problem of cigarette smoke in public places is still a problem among the community. To solve this problem, this research will design and implement a device capable of detecting the presence of cigarette smoke and its temperature using the MQ-135 smoke sensor and the DS18B20 temperature sensor. If cigarette smoke is detected, the wifi module receives data on the Arduino, then the LCDs the smoke, temperature, defuzzification, and speed values on the fan simultaneously and the wifi transfer module on Android / Hp is displayed on the LCD and the fan. functions automatically to inhale or absorb cigarette smoke in the room and cigarette smoke is filtered out through the air neutralizer so that the air that comes out of the room is clean.
