Negative Oxygen Ion Monitoring System: Principle, Components and Application Value

An oxygen atom with a negative charge is known as a negative oxygen ion. It can combine with harmful substances in the air, such as dust, germs, and smoke, causing these substances to settle or be neutralized. This process purifies the air and increases oxygen content. The concentration of negative ions in the air is a key indicator for evaluating air quality, and the World Health Organization (WHO) has established relevant standards for the negative ion concentration in fresh air.

Within the Negative Oxygen Ion Monitoring System, the negative oxygen ion monitoring station—suitable for outdoor environments like scenic spots, parks, and forests—is a core component. It includes parts such as a negative oxygen ion detector, a data acquisition host, a mounting and protective bracket, a solar power supply system, and a large LED display screen. It can be expanded with various meteorological sensors (for temperature, humidity, air pressure, wind speed, etc.) to conduct real-time monitoring.

Relying on IoT communication technologies such as RS485, Ethernet, and 4G, and supported by an environmental monitoring cloud platform, this type of monitoring station builds an intelligent environmental monitoring and management system integrating multiple functions: remote monitoring, large LED screen display, and information release via large LED screens. The negative oxygen ion online monitoring system can continuously monitor air quality 24/7 and provide real-time data on negative oxygen ion concentration. Additionally, the system can expand monitoring items, including air temperature, humidity, PM2.5, PM10, atmospheric pressure, oxygen content, noise, wind speed, and wind direction, to meet the monitoring needs of different environments.

The large LED screen supports two communication methods:

Wired local access: It obtains real-time data from the negative oxygen ion monitoring station through RS485 communication.

Remote access: It acquires cloud data via 4G or Ethernet communication and displays it on-site.

The negative oxygen ion LED screen delivers significant effects in enhancing the tourist experience, improving service quality, creating commercial value, and ensuring tourist safety. It has become an essential facility for modern scenic spots. The negative oxygen ion detector can conduct real-time monitoring of negative oxygen ion concentration in places such as scenic spots, parks, forests, and indoor spaces. It holds great significance in evaluating the air quality of monitored locations, helping improve living environments, and safeguarding public health.
