Air Quality Outdoor Sensor for Environmental Monitoring

An air quality outdoor sensor is a device used to monitor atmospheric environmental parameters in real time. It primarily measures the concentrations of particulate matter such as PM2.5 and PM10, and can be expanded to monitor gases such as CO, NO₂, SO₂, O₃, and VOCs, as well as meteorological parameters including temperature, humidity, wind speed, and wind direction. These devices typically utilize principles such as laser scattering and feature high precision, high integration, and remote transmission capabilities. They are widely used in scenarios such as smart cities, construction site dust monitoring, industrial parks, and roadside environmental monitoring.
