Negative Oxygen Ion Monitoring Station: Smart Monitoring in Ecological Areas

In ecologically beautiful areas, such as forests, mountain streams, rivers, lakes, seas, and around waterfalls, people often feel that the air is particularly fresh. This is mainly due to the relatively high content of negative oxygen ions in the air in these places. Negative oxygen ions are oxygen atoms with a negative charge. They can combine with harmful substances in the air such as dust, germs, and smoke, prompting them to settle or neutralize, thus achieving the effects of purifying the air and increasing the oxygen content. Therefore, they are known as the "air vitamins" or "air cleaners", and they are also an important indicator for measuring air quality, with clear standards set by the World Health Organization.

However, with the acceleration of the industrialization process, the air quality in many regions has been severely affected and has not yet fully recovered. According to calculations by the environmental department, in large cities, especially heavy industrial cities, the content of negative oxygen ions in each cubic centimeter of air is only about 200.

In order to more accurately monitor the concentration of negative oxygen ions, evaluate air quality, and provide support for ecological protection and tourism development, negative oxygen ion monitoring stations have been launched in the market. This device is composed of a negative ion detection device, a data acquisition host, an installation protection bracket, a solar power supply system, an LED display screen, etc. Among them, the negative ion detection device adopts a cylindrical ion collection unit and an ultra-micro current signal processing unit. It has high ion charge conversion efficiency and stable charge collection performance. It also supports parameter setting through buttons, is easy to operate, and can meet the monitoring needs of users.

Considering the complex and changeable outdoor environment and that the content of negative oxygen ions is easily affected by weather changes, a single monitoring method is difficult to meet the requirements of environmental monitoring. Therefore, users can expand various meteorological sensors according to project requirements to achieve real-time monitoring of a variety of meteorological elements such as air temperature and humidity, wind speed, wind direction, carbon dioxide, atmospheric pressure, illumination, rain and snow conditions, ultraviolet rays, total radiation, carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, and hydrogen sulfide.

The Negative oxygen ion monitoring station, with the help of Internet of Things communication technologies such as RS485, Ethernet, and 4G, relies on the environmental monitoring cloud platform to build a multi-functional integrated intelligent environmental monitoring and management system. Users can log in to the environmental monitoring cloud platform through their mobile phones or computers to remotely view data and manage devices. This platform has access methods such as the computer terminal, mobile APP, and WeChat official account, and can achieve functions such as real-time data viewing, over-limit alarm, historical data and curve query/export, device positioning, intelligent control, video monitoring and capture, account grading, and large-screen visualization. Users can set dangerous warning values for various monitoring elements in the platform. Once the real-time monitoring data exceeds the limit, the platform will remind users through methods such as the data turning red, pop-up windows, and sounds. At the same time, it can also send remote alarms through phone calls, text messages, emails, and WeChat push.

The negative oxygen ion LED display screen is an important facility in modern scenic areas and plays an important role in enhancing the tourist experience, improving service levels, and ensuring the safety of tourists. The LED display screen can obtain the real-time data of the Negative oxygen ion monitoring station through RS485 communication in the "nearby wired mode", and can also obtain the cloud data through 4G or Ethernet network communication in the "remote mode" for on-site display. It can simultaneously display the content of multiple monitoring elements and the time (year, month, day, hour, minute, and day of the week), and can be directly set to display or not through the mobile APP configuration software.
