Negative Oxygen Ion Monitoring System: Health Implications and Technological Applications

In an era where technological waves continue to surge and innovative achievements emerge endlessly, the public's environmental awareness has grown increasingly sophisticated, and their concern for ambient air quality has reached an unprecedented level. In the fast-paced modern life, as the internet deeply integrates into work and daily routines, the resulting health hazards have become increasingly prominent. Positive ions in the air may trigger discomforts such as insomnia, headaches, restlessness, and elevated blood pressure. In stark contrast, negative air ions in nature are the "health code" behind many longevity villages. These negative ions enter the human body through the lungs and act via the nervous and blood circulation systems, bringing numerous health benefits.

Negative air ions, also known as negative oxygen ions, essentially refer to oxygen ions that carry a negative charge by gaining one or more electrons. Air is primarily composed of nitrogen, oxygen, carbon dioxide, and water vapor, with nitrogen accounting for 78%, oxygen 21%, and carbon dioxide only 0.03%. Since nitrogen has low affinity for electrons and oxygen content is 700 times that of carbon dioxide, most negative ions in the air are negative oxygen ions, which are formed by the combination of oxygen molecules and free electrons. Medical research shows that negative air oxygen ions are known as the "vitamins of the air." They can not only decompose and neutralize harmful gases in the air but also regulate human physiological functions, relieve fatigue, improve sleep, play a positive role in the prevention and improvement of respiratory and cardiovascular diseases, and even enhance appetite and enhance skin elasticity. In addition, negative oxygen ions have sedative, analgesic, antitussive, and antipruritic effects, as well as certain effects on blood pressure regulation and diuresis. Natural phenomena such as lightning, the photoelectric effect, and fountains and waterfalls can all ionize the surrounding air, thereby generating negative oxygen ions. When the concentration of negative oxygen ions in the environment increases, people feel physically and mentally refreshed.

Spending long periods in enclosed urban spaces often makes people feel dizzy, but when entering forests, coastal areas, or near waterfalls, they immediately feel refreshed—this is the wonderful effect of negative air ions at work. Negative ions excel in purifying the air, reducing the harm of secondhand smoke, preventing respiratory diseases, improving sleep quality, anti-oxidation and anti-aging, eliminating free radicals in the body, and reducing blood viscosity. They have earned reputations in the medical field such as "vita-oxygen," "air vitamins," and "longevity factors."

The Negative Oxygen Ion Monitoring System is highly functional, capable of simultaneously monitoring atmospheric negative oxygen ion concentration and multiple environmental factors such as temperature, humidity, PM2.5, PM10, wind speed, wind direction, and air pressure. With the air negative ion automatic measurement system, it is possible to track the variation patterns of negative ion concentration across different regions, time periods, weather conditions, and seasons. The system realizes a fully automated and intelligent process from data collection, transmission, processing, to publication, providing key data support for ecological city construction. Its functional configuration is flexible and can be adjusted according to user needs. It supports 24-hour uninterrupted monitoring, is equipped with professional installation brackets and upright poles, and is easy to install. It supports on-site real-time data visualization and provides remote cloud platform monitoring and mobile client query services, which greatly reduces the difficulty of post-operation and maintenance. It strongly promotes the construction of smart monitoring and smart environmental protection, helping to create high-quality tourism and living environments.

The Negative Oxygen Ion Monitoring System adopts GPRS wireless data transmission technology, completing data transmission through the IoT card traffic on the wireless transmission module. In the link of remote information display and publication, data is first converted into GPRS network signals via the internet, then sent to the wireless transmission module through the GPRS network, and finally forwarded by the wireless module to the LED display for presentation.
