Air quality monitor can collect various outdoor ambient air quality data around the clock

Air quality monitor primarily focuses on all-weather negative oxygen ion detection, and can be expanded to monitor temperature, humidity, PM2.5, and PM10. Its modular sensors are easy to replace, and it supports on-site readings and remote viewing through multiple channels, adaptable to various outdoor locations.

There are many Air quality monitor models available on the market. Home-use models tend to detect indoor formaldehyde and volatile organic compounds, while outdoor-specific models prioritize long-term uninterrupted operation, replaceable sensors, and remote data transmission capabilities, making them suitable for long-term outdoor environmental monitoring. The core function of the outdoor-specific device introduced here is continuous all-weather monitoring of negative oxygen ion content. Users can add corresponding sensor components according to their site monitoring needs to expand monitoring to include conventional meteorological and air pollutant monitoring items such as air temperature, air humidity, PM2.5, and PM10 particulate matter.

The Air quality monitor system utilizes a modular structure, allowing each individual sensor to be disassembled and replaced separately. This simplifies maintenance after sensor aging or parameter deviations, eliminating the need for complete disassembly and reassembly. A dedicated outdoor mounting bracket is included, allowing personnel to directly read all current monitoring values on the onboard LED display after installation. The system also features a data transmission module, enabling monitoring personnel to access real-time data and remotely manage equipment operation anytime, anywhere via a cloud platform, web interface, or WeChat official account.

The Air quality monitor system ensures accurate detection based on mature sensing principles. The temperature sensor uses the diode junction voltage method, covering a measurement range of -40 to 60°C; the humidity sensor employs capacitive detection; PM2.5 and PM10 particulate matter concentrations are calculated using light scattering principles; and negative oxygen ions are measured using a cylindrical electrode inhalation sensor. All components offer sufficient resolution, keeping measurement errors within a controllable range.

The Air quality monitor device can be deployed in various outdoor and public areas. Tourist attractions, wetland parks, forest parks, ecological farms, waterfall parks, and nature reserves can all rely on it to record the level of negative oxygen ions in the environment, showcasing the quality of the regional ecological environment. In sales centers and school grounds, the device can be deployed to monitor the air environment in real time, providing objective data support for environmental management. The overall equipment combines the advantages of convenient installation, simple operation and maintenance, and multi-terminal data viewing, making it a practical device for routine outdoor air quality monitoring.
