Design of The Smoke Level Measuring Device and Cigarette Smoke Control Device in The Smoking Area on Campus

Abstract

A cigarette smoke controller is intended to control the level of cigarette smoke in a room. Smoking areas are usually located in small, confined spaces. If the smoking area is located inside a building, the air quality in the smoking area will be very worrying, especially if there are several people in the room. The design of this cigarette smoke controller is intended to be able to control the air quality in the room. Cigarette smoke in the smoking area is controlled by a fan or blower that can be turned on automatically. All of these can be controlled by a microcontroller based on the Arduino Uno microcontroller. The MQ-2 sensor is used to measure the smoke level in the air, and the DS18B20 temperature sensor is used to measure the room temperature. To display the measurement values from the sensors used, a 16x2 character display is chosen. This design is intended to control the AC fan used to neutralize cigarette smoke levels in the air, whether it should be on or off, whether to increase the fan rotation speed, or keep it at a low speed. All of these functions must be implemented to obtain good research results.
