Seeed Studio (101020613) Sensor Board, HM3301, Dust Sensor, Arduino Board

The Grove Laser PM2.5 sensor (HM3301) is a new generation of laser dustdetection sensor, which is used for continuous and real-time detection of dustin the air. With its stable output, low noise, and ultra-low power consumption,it is suitable for air conditioners, intelligent air purifiers, and other airquality-related IoT projects. Different from the traditional pumping dustdetection sensor, the HM-3301 innovatively uses fan blades to drive air, and theair flowing through the detection chamber is used as a test sample to perform areal-time and continuous test on dust of different particle sizes in the air.Specifications:- Silicon Core Number: HM3301- For Use With: Arduino Board- Kit Contents: Grove - Laser PM2.5 Dust Sensor Board HM3301, Grove Cable- Real-time continuous detection of dust concentration in the air- High sensitivity on dust particles of 0.3 m or greater- Based on laser light scattering technology, readings are accurate, stable, andconsistent- Low noise and ultra-low power consumption
