Based on the laser scattering principle, this sensor accurately detects particles ranging from 0.3μm to 10μm, and real-time monitors the concentrations of PM2.5/PM10/PM1.0 (measuring range: 0-1000μg/m³, resolution: 1μg/m³). It features a built-in self-calibration function upon startup. Supporting the standard LoRaWAN protocol, it is compatible with multiple frequency bands and OTAA Class A/C modes, ensuring stable data transmission. With a default data collection cycle of 10 seconds and reporting cycle of 5 minutes, it allows flexible configuration of threshold triggers and the number of abnormal reports. Adaptable to a wide temperature range of -20℃~60℃ and easy to install, it is widely used for dust monitoring in outdoor weather stations, industrial plants, libraries and other places, providing reliable data support for air quality management.
