How does AQMS Work?

The ambient air quality monitoring system can be configured with optional measurement modules for gases, particulate matter, and meteorological parameters based on user needs. It is a new, low-cost, intelligent air quality monitoring device.

The AQMS air quality monitoring system consists of four components: a sampling device, analyzers, a calibration device, and a data acquisition system. Gaseous pollutant analyzers include analyzers for SO2, NO, O3, CO, VOCs, laser gas (HCl, HF, NH3), and a NO2 analyzer (CAPS cavity attenuation phase shift spectrometer). Particulate matter analyzers include PM2.5, PM10, and an extinction analyzer (aerosol analyzer).

The system workflow is as follows:

• Data Acquisition System: Utilizes sensors and monitoring equipment to monitor the concentrations of various pollutants (such as PM2.5, PM10, NO2, SO2, CO, and O3) in real time.
• Data Transmission and Storage: Collected data is transmitted to a central processing system via a network or other communication method, where it is stored for analysis and retrieval. Data Analysis and Processing: Utilizes statistical and computational methods to process data and generate air quality reports, trend charts, and air quality assessments.
• Alarm and Feedback Mechanism: When pollutant levels exceed safety thresholds, automatic alarms are triggered, notifying relevant departments to take urgent action.
• Decision Support System: Provides decision support for air quality management, assisting governments, environmental protection agencies, and businesses in developing pollution control strategies.

Typical Applications
