The Grove - Laser PM2.5 Sensor (HM3301) represents a new generation of laser dust detection sensors, designed for continuous and real-time dust detection in the air. Unlike traditional pumping dust detection sensors, the HM-3301 innovatively uses fan blades to drive air, using the air flowing through the detection chamber as a test sample. This module is appropriate for use in a range of applications and devices, including dust detectors, smart air purifiers, intelligent air conditioners, smart ventilation fans, air quality testing, haze meters and various environmental monitoring systems.
