Environmental Monitoring Station provides real-time display of negative oxygen ion concentrations in the air

Environmental Monitoring Station utilizes a cylindrical electrode aspiration-type sensor with a measurement range of 0 to 100,000 ions/cm³ and an accuracy of ±10%, enabling automated, all-weather monitoring. The device supports the addition of extended monitoring parameters—such as temperature, humidity, PM2.5, PM10, wind speed, and wind direction—and uploads data to a cloud platform via 4G or fiber-optic connections.

Environmental Monitoring Station is an automated instrument designed for the real-time measurement of negative oxygen ion concentrations in the air. The device employs a cylindrical electrode aspiration-type sensor as its core detection component, operating based on the principle of capacitive aspiration. Air enters the sensor chamber through an intake port; under the influence of an electric field, negative oxygen ions are collected, generating a micro-current signal whose intensity is directly proportional to the negative oxygen ion concentration. The sensor features a built-in high-precision microprocessor that applies algorithms to filter, amplify, and temperature-compensate the current signal, thereby eliminating the impact of environmental interference factors and ensuring data accuracy.

The negative oxygen ion measurement range of Environmental Monitoring Station spans from 0 to 100,000 ions/cm³, with a measurement error margin of no more than ±10%, a resolution of 1 ion/cm³, and a response time of less than 30 seconds. The device operates automatically around the clock without the need for manual supervision; once powered on, it immediately begins continuous monitoring and automatically saves data. Regarding field deployment, the device is equipped with a professional mounting bracket, allowing for flexible installation via either a pole-mount or wall-mount configuration. Its main structural housing is constructed from carbon steel and features composite sealing strips, achieving an IP65 protection rating and enabling operation within an environmental temperature range of -40°C to 60°C.

In addition to monitoring negative oxygen ion concentrations, Environmental Monitoring Station can be flexibly expanded to include other monitoring parameters based on user requirements—including meteorological factors such as air temperature, humidity, PM2.5, PM10, atmospheric pressure, oxygen content, noise levels, wind speed, and wind direction. The device features a modular structural design wherein each sensor component can be individually replaced, facilitating ease of maintenance and functional upgrades in the future. Once collected, data is transmitted to a cloud-based platform via transmission methods such as 4G or fiber optics; users can directly read real-time data on the device's on-site LED display or remotely access and view data via the cloud platform, a web interface, or a WeChat Official Account. The cloud-based platform supports functions such as data storage, historical data retrieval, report generation, and trend analysis; furthermore, the system automatically issues alerts whenever monitored values exceed pre-configured thresholds. This device is widely deployed for air quality monitoring and ecological benefit assessment in various settings, including tourist attractions, forest parks, wetland parks, nature reserves, and wellness retreats.
