Introduction

In a class filled with many students, air comfort is very important to maintain the concentration of learning. To improve learning experiences, an automatic room fragrance tool was developed that uses Arduino technology. This tool is equipped with a photodiode sensor that detects the presence of users in the room. When someone enters or leaves the room, the sensor will send a signal to the microcontroller, which then displays data on the LCD screen.

How the Tool Works

The work system of this tool begins when the device is connected to the adapter to the power source. Once connected, the sensor will begin to count the number of people who enter and leave the class. Every time someone enters the room, the number of visitors increases, while every time a person comes out, the number of visitors is reduced.

This system has three levels of fragrant spraying settings based on the number of indoor users:

Level 1: More than 50 users

The tool will spray perfume every minute.
This setting is ideal for large classrooms or lecture halls where many students gather.

Level 2: Between 20 to 50 users

The tool will spray perfume every 5 minutes.
This setting is suitable for medium-sized classrooms or study rooms where a moderate number of students gather.

Level 3: Less than 20 users

The tool will spray perfume every 10 minutes.
This setting is ideal for small classrooms or private study rooms where a limited number of students gather.

Analysis and Explanation

The importance of using this Arduino-based automatic room fragrance tool is not only located in comfort, but also efficiency in the use of fragrances. With this automatic system, spraying can be adjusted to the level of user density, so as to avoid the waste of fragrances that can occur if done manually.

In addition, this tool can also be a practical solution for classroom managers or study rooms that often face unpleasant odor problems, especially when many students gather in one room. With a simple design and easy to implement, this project can be an inspiration for other automatic system developers.

Benefits of the System

The control system of this room fragrance device not only serves to maintain the freshness of the air in the classroom, but also increases the comfort and concentration of students in learning. This innovation shows that technology can be applied in various aspects of life, including in creating a better learning environment.
