Designing Detection of Arduino Uno Cigarette Smoke with Sound Output and Automatic Lights: A Step Towards a Healthier Environment

With the increasing number of closed room users dominated by smokers, the negative impact on the health of both smokers and non-smokers is increasingly felt. The problem of cigarette smoke in public places is still a warm issue in the community, especially because of the lack of strict sanctions and fear of many people to reprimand smokers. As a solution to overcome this problem, this final project aims to design and realize a device that is able to detect cigarette smoke automatically using the MQ-7 sensor.

The Need for Cigarette Smoke Detection

Cigarette smoke is a major contributor to indoor air pollution, and its presence can have serious health consequences for both smokers and non-smokers. According to the World Health Organization (WHO), exposure to secondhand smoke can cause heart disease, stroke, and lung cancer, among other health problems. In addition, cigarette smoke can also damage furniture, carpets, and other household items, leading to costly repairs and replacements.

The Role of Arduino in Cigarette Smoke Detection

Arduino is an open-source electronic platform that has revolutionized the way we design and build electronic devices. By using Arduino Uno, which is equipped with a microcontroller from Atmel, this tool can be programmed through a computer to carry out its functions. The MQ-7 sensor, which is used in this project, is designed to detect cigarette smoke with accuracy reaching 99.89% at a minimum concentration of 60 ppm. This allows tools to quickly and accurately detect the presence of cigarette smoke that can interfere with the comfort of space.

The Benefits of Cigarette Smoke Detection with Arduino

The presence of this arduino-based cigarette smoke detection device can provide several advantages, including:

Improved Health: By detecting and reminding smokers not to smoke, this tool can help create a healthier environment for everyone, especially for those who are sensitive to cigarette smoke.
Automation: With the automatic feature turn off the lights, this tool not only reminds but also gives a quick reaction to the presence of smoke, creating a more comfortable and safe atmosphere.
Effectiveness: Using a clear sound alarm and dead lights can reduce the comfort of smokers, thus motivating them to leave the room when they want to smoke.

The Design and Implementation of the Cigarette Smoke Detection Device

The design of the cigarette smoke detection device is based on the use of the MQ-7 sensor, which is connected to the Arduino Uno microcontroller. The sensor is designed to detect the presence of cigarette smoke and send a signal to the microcontroller, which then triggers the sound alarm and turns off the lights. The device is powered by a battery and has a simple and compact design that makes it easy to install and use.

The Sound Output and Automatic Lights Features

The device has two main features: sound output and automatic lights. The sound output feature uses a speaker to produce a clear and loud alarm sound when cigarette smoke is detected. The automatic lights feature uses a relay to turn off the lights when cigarette smoke is detected, creating a more comfortable and safe atmosphere.

The Advantages of Using Arduino in Cigarette Smoke Detection

Using Arduino in cigarette smoke detection has several advantages, including:

Ease of Use: Arduino is a user-friendly platform that makes it easy to design and build electronic devices.
Flexibility: Arduino can be programmed to perform a wide range of tasks, making it a versatile platform for electronic device design.
Cost-Effectiveness: Arduino is an open-source platform, which means that it is free to use and can be customized to meet specific needs.

Conclusion

Design Detection of Arduino Uno cigarette smoke with sound output and automatic lights is a step forward to overcome the problem of cigarette smoke in a closed room. With the right technology and effective design, this tool is expected to increase public awareness about the dangers of smoking and encourage the creation of better smoke-free space. This tool will not only provide benefits for individual health, but also creates a safer and more comfortable environment for all visitors.

Future Work

Future work on this project can include:

Improving the Accuracy of the MQ-7 Sensor: The MQ-7 sensor has a high accuracy rate, but it can be improved further to detect cigarette smoke at lower concentrations.
Adding More Features: The device can be designed to include more features, such as a display screen or a mobile app, to provide more information and feedback to users.
Scaling Up the Design: The design can be scaled up to detect cigarette smoke in larger spaces, such as offices or public buildings.
