Arduino for Everyone: Environmental Sensors Preface
Air is central to our lives, and society cannot function with held breaths. Fine dust and air pollution are worsening and are causing significant damage to society. Air is life-giving, but if we keep producing pollution that dirties the air, it becomes something that endangers all lives. Air pollution and climate change has become an urgent problem for mankind to solve. Air pollutants contaminate air, water, soil, etc., changing the ecosystem and threatening our habitats.
The Greenpeace Southeast Asia and the Centre for Energy and Clean Air Research (CREA) was the first to measure the global cost of air pollution from fossil fuels. They announced that it would reach about US$8 billion per day (KRW 8.676 trillion). In addition, about 3.3% of the world's gross domestic product (GDP), or $2.9 trillion (approximately KRW 3,145 trillion as of December 9, 2020), was found to be causing economic losses. The OECD predicts that the social cost of air pollution in Korea is currently around 10 trillion won, but it will reach 20 trillion won by 2060. Korea's air pollution is the worst among OECD members. In addition, as of 2018, 4.5 million people die prematurely every year due to air pollution. This includes 1.8 million in China, 1 million in India, and 40,000 in Korea. The number of patients with asthma and respiratory diseases has increased, and hospital visits and work absences have been reported in billions.
According to a study, 8.8 million people die from heart attacks and strokes every year worldwide. These deaths have been linked to air pollution such as fine dust. According to a report by researchers at the Mainz Medical School and the Max Planck Institute in Germany, more than 800,000 people die every year from cardiovascular diseases caused by air pollution in Europe alone, with air pollution caused by automobile emissions and factory fumes. They expected that those who live in affected areas have their lifespan cut short by an average of 2.2 years.
Modern people spend 90% of their lives indoors. One of the trending keywords in 2021 is "Omni-layered homes," meaning houses with multi functional systems. Because of the Coronavirus, we spend more time indoors. This means that activities that we used to do outside must now be done in our homes. For example, we can enjoy home exercise and can work from home. We can also transform our homes to a classroom one day, and a cinema on another.
We are spending considerable time in our homes, and yet we do not realize how important the indoor air is to our health. Depending on the space and materials used for our homes and other buildings, we can experience other indoor environmental problems such as Sick Building Syndrome, which can be as severe as air pollution.
Every spring, we hear about fine dust, yellow dust, and smog on the news. What exactly does air pollution, which has now become a serious problem, mean for us? The World Health Organization (WHO) states that air pollution is the presence of artificially emitted pollutants in the atmosphere, causing discomfort to local residents, plants and animals based on the pollutant concentration and exposure length. Problems such as fine dust and yellow dust, as well as ozone layer depletion, acid rain, and global warming are considered different concepts stemming from air pollution, are largely in the category of air pollution. Air pollutants include fine dust, ultrafine dust, ozone (O),), carbon monoxide (CO2), carbon dioxide (CO2), formaldehyde, volatile organic compounds (VOCs), nitrogen dioxide (NO2), and sulfur dioxide (SO2). These gases are all artificially emitted substances caused by human activities.
Air pollution is a man-made environmental problem. The problem of air pollution became serious after the industrial revolution, when the use of fossil fuels soared. Air pollution has a fatal effect on people's health. For example, it is the main cause of chronic respiratory diseases such as pneumonia and asthma, and it can also cause lung cancer. Also, studies have reported that fine dust, a type of air pollution, exacerbates cardiovascular disease. The problem becomes even more severe in urban areas.
Effects on the human body from indoor air pollution occur depending on the characteristics of the pollutants, environmental factors, and the health and immunity of each individual. Therefore, people who are sensitive to air pollution are making great efforts to protect their health from air pollution. When the air condition is not good, refrain from going out as much as possible, and wear a health mask if going outdoors. After going outdoors, people wash themselves clean and eat fruits and vegetables rich in water, vitamin C, etc. On days when the atmosphere is good, care is taken for indoor air quality, such as ventilation and indoor water cleaning. People use air purifiers to keep the air fresh and clean. After all, we have now lost our freedom to breathe fresh air outdoors. We want to breathe fresh air.
We are currently living in a toxic, air-polluted world, but we do not have to. Everyone has the right to breath clean, fresh air, but it does not come easy. All of us must do our best to reduce air pollution and protect our health.
This book was written to help you and your family breath easier and live healthier lives.
You will learn how Arduino and air quality measurement sensors allow us to measure the conditions of our surroundings. By the end of the book, you will be able to understand and use 18 Arduino environmental sensors. Chapter 2 covers the fine dust sensor, Chapter 3 indoor air environmental sensors, Chapter 4 outdoor air environmental sensors, and Chapter 5 covers how air environmental sensors can be calibrated to check air quality. Finally, Chapter 6 goes over four projects to measure the atmospheric environment. You will make simple fine dust and temperature-humidity sensors and find applications for them. For example, by using sensors, you can intuitively know the aair quality in for stages: good, normal, bad, and very bad. This information can be used to control air-conditioning or heating and cooling. In each project, you will be able to display air quality data on LCD, OLED screens and by connecting to Wi-Fi, Bluetooth, or RD, create your own IoT in your house.
Big Data is the foundation of the Fourth Industrial Revolution. Artificial intelligence (AI, deep learning, machine learning, etc.) is powered by Big Data, and is being applied in various fields. In the Big Data Era, there is a flood of data from the Internet, and from the huge amounts of data produced by sensors used by individuals, factories, public institutions, and even family homes.
6G networks are now being developed, and faster Wi-Fi 6E (802.11ax), Bluetooth, and UWB (ultra-wideband) communication speeds allow data to be collected and analyzed more quickly. M2M (Machine to Machine), Internet of Things (IoT), and Internet of Everything (IoE) are in full force and require robust sensors to capture and study all the data produced. Sensors are also seeing increased use in all aspects of our lives. They must be small, robust, durable. inexpensive, and have low power consumption.
As IoT begin to dominate our interactions with one another (Hyper Connected Society), an estimated 100 billion objects will be connected and able to communicate through the Internet. Additionally, trillions of sensors will be installed, and the global sensor market is expected to reach a value of 220 trillion won. Smart tools are also being developed that can connect with IoT and make our lives more convenient. The Fourth Industrial Revolution all starts with robust sensors that can quickly and accurately measure data.
We live under the influence of air, and along with animals and plants, we are currently being exposed to air pollution both indoors and outdoors. If we can combine sensors with Big Data, we would be able to create more meaningful data from daily weather data such as air quality, temperature, humidity, air pressure, wind speed, etc.
Sensors are the seeds of the Fourth Industrial Revolution. If we can use sensors to capture and analyze Big Data from air pollution, we can create new technological industries focused on manufacturing these environmental sensors. For example, if we can predict the number of atopic dermatitis patients per month based on weather and air pollutant information and analyzing them through business models, we can create new markets. The possibilities are limitless.
With the sensors covered in this book, you will be able to measure air quality and imagine and create even more uses for these sensors.
