AQI is a micro air quality station with an exquisite design. It adopts the modular, digital, and solid-state design concept for its sensors, making it easy for various configurations and disassembly. It can measure six key elements of air quality. It uses electro-chemical sensors and an optical particle counter to monitor air pollution and particles. The main measurement and monitoring elements are SO2 , NO2 , CO, O3 , PM2.5, and PM10. AQI can be widely used in many applications including smart city, road weather, agriculture, forestry and plant protection.
