Grove - Laser PM2.5 Dust Sensor - Arduino Compatible - HM3301 FactoryDirect Digital FPV Air Unit: DJIThe Grove Laser PM2. 5 Sensor (HM3301) is a new generation of laser dust detection sensor, which is used for continuous and real time detection of dust in the air. With its stable output, low noise, and ultra low power consumption, it is suitable for air conditioners, intelligent air purifiers, and other air quality related IoT projects. Different from the traditional pumping dust detection sensor, the HM 3301 innovatively uses fan blades to drive
