Artificial intelligence (AI) technology, in particular, has sparked widespread attention. However, these advances are eclipsed by environmental problems that increase more. The sad reality of air pollution, which is impacted by elements such as temperature, humidity, fine particulate matter (PM2.5), and CO2 concentration, calls for prompt action.
Hanoi's air quality is an especially frightening example. In early March, the city continuously rated among the top three most polluted cities in the world, topping the list on March 5th with an extremely poor air quality index (AQI) of 241. On March 5th, the Pam Air pollution monitoring program detected an alarming air quality index (AQI) of 429 at the Vuon Dau - Trau Quy measurement station (Gia Lam area). This reading falls under the "brown" threshold, which is perilously near to the critical level on the AQI scale (usually 500).
Concerningly, high pollution levels were observed at additional monitoring stations, including Doi Can (Ba Dinh)[3] with an AQI of 254, Dai Mo (Nam Tu Liem) with an AQI of 243, and Dong Anh town (Dong Anh district) with an AQI of 296. These findings underline the critical need for effective solutions to reduce air pollution and manage temperature. Traditional methods of monitoring and regulating these environmental parameters are frequently labor-intensive, subject to human error, and restricted in scope. Clearly, a more efficient and consistent strategy is required.
The pressing need for better indoor air quality and temperature control highlights the need of creating a smart and automated home management system. Such a system would constantly monitor and regulate electrical appliances, humidity levels, and temperature to ensure a comfortable and energy-efficient living environment. The Internet of Things (IoT) technology provides an ideal alternative for reaching this aim. IoT enables the seamless integration of sensors, controllers, and software solutions, making home automation systems more accessible and usable than ever before.
6 My idea intends to save money while developing a strong, yet simple, and user-friendly solution for families to control their smart gadgets and appliances. The key functionality will deliver real-time information on environmental conditions in the house. Users will also benefit from remote access features, which will allow them to operate their smart devices from anywhere. This system will combine existing technology with creative ideas to provide people total control over their living environment.
Finally, the idea proposes an optimum control system that promotes user comfort and energy efficiency. The system will adapt settings based on your preferences, resulting in a personalized living experience that is both pleasant and energy efficient. This project covers the common issues of building and implementing systems to manage air temperature, humidity, and fine dust in a straightforward and precise manner. It gives homeowners more control over their living space by streamlining the procedure.
This system offers practical solutions to improve comfort, performance, energy savings, and overall convenience in existing houses.2 Overview: In today's world, when air quality is becoming increasingly important, particularly in metropolitan areas, keeping a healthy and comfortable interior atmosphere is critical. This requirement is addressed by the project "Automated Indoor Air Quality Monitoring, Air Quality Improvement and Notification System" .Using the information I gained in school, as well as spontaneously exploring and learning online, this system leverages the potential of the Internet of Things (IoT) to offer users with real-time data on crucial indoor air quality factors. The system offers a complete solution for monitoring and regulating indoor air quality by combining the embedded software with an easy-to-use website. The system's fundamental role is to continually detect essential air quality indicators such as temperature, humidity, fine particles (PM2.5), and carbon dioxide (CO2).
These metrics are crucial for determining the overall health of the indoor environment. Rising temperatures and humidity can create discomfort and encourage mold growth, whilst small dust particles can trigger allergies and respiratory issues. High CO2 levels might also cause tiredness and headaches. The collected data is not only shown locally, but also 7 posted to a dedicated website, which users may view remotely.
This online interface gives a clear and succinct summary of air quality data in a user-friendly style. Consider being able to monitor the air quality in your house using your phone while at work.This remote access enables consumers to make educated decisions regarding their home environment even when they are not present. The system does not stop at monitoring. It has the possibility for future development, such as integration with air filtration devices or smart ventilation systems.
This connection will enable the system to not only alert users to bad air quality, but also take automatic efforts to enhance it. Consider a system that automatically activates an air purifier whenever excessive PM2.5 levels are detected. This effort is a significant step toward building smarter, healthier homes. By offering real-time data, remote access, and automation capabilities, users may adjust indoor air quality and create more pleasant and healthful living conditions.
My technology has the potential to simplify other existing solutions in the globe, such as the Huma-i HI-150 air quality meter (which gives high-resolution measurement displays on an LED screen). Highly accurate cloud storage and analysis), Xiaomi PM2.5 (connects to WiFi, synchronizes with smartphone, accurately measures PM2.5 particle density), Tenmars TM-280 (PM2.5 index and LED lights display air quality, luxurious design with materials High-quality ABS, accurate laser sensor, and fast presentation of findings. The preceding solutions now lack a display and control mechanism on the website for easy alarming and controlling.3 Reason: The quality of indoor air has a significant impact on people's health and wellbeing. Keeping indoor air quality in excellent condition has grown increasingly important as people spend more and more time indoors, whether at work or at home.
Nevertheless, the real-time and continuous monitoring of different air contaminants is limited by the design of the present indoor air quality monitoring devices. By creating an automated air quality monitoring system that can assess air quality parameters including particulate matter, carbon monoxide, volatile organic compounds, etc. on a regular basis, the suggested system seeks to close this gap. Additionally, the system will use data analysis 8 to identify low levels of indoor air quality and send out messages when necessary to implement inexpensive air purification techniques like ventilation or filters.

on a regular basis, the suggested system seeks to close this gap. Additionally, the system will use data analysis to identify low levels of indoor air quality and send out messages when necessary to implement inexpensive air purification techniques like ventilation or filters. The primary purpose of this project is to create a reliable communication link between various sensor circuits. These circuits, which will be explained in greater detail later, will continually monitor environmental factors such as temperature, humidity, and fine dust in the essential air and designated space.
This data is then analyzed and turned into a comprehensive air dataset that represents total indoor air quality and is kept for presentation on a specific website, along with the parameters. The project has a clear and distinct display. The initiative has a two-pronged strategy to optimize user advantages. First, the gathered air quality data will be uploaded to a dedicated website.
This online interface will allow customers to monitor and regulate their home environment remotely, providing them with real-time information about its health. Imagine checking the air quality from your smartphone, regardless of where you are. This enables people to make educated decisions about their living environment even when they are not present. Second, the initiative delves further, evaluating the acquired data to find possible fire threats.
By monitoring temperature and other pertinent characteristics, the device can detect early warning indications of a fire. This proactive strategy allows for prompt action, has the ability to reduce property damage, and, most importantly, safeguard human health; nevertheless, the necessity of comfort and control will assist promote user advantages. My project is used in a minimalist way due to the cost and size of the project, the 9 coverage is also thoroughly guaranteed so that real data can be updated in detail and intuitively. current air the user receives 1.4 Research limitation: This study endeavor recognizes the inherent limits of the scale and technology used.
Initial testing and assessment of the indoor air quality (IAQ) monitoring system will be limited to controlled conditions on a small scale, such as dormitory rooms, university offices, or labs. To maximize resource allocation, the system will first use low-cost sensor modules for temperature, humidity, and particle matter, with an emphasis on monitoring critical air pollutants. More sophisticated sensors have the potential to be integrated, but future funding sources will determine this.
