The 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 air, and the air flowing through the detection chamber is used as a test sample to perform a real-time and continuous test on dust of different particle sizes in the air.

• Real-time & continuous detection of dust concentration in the air
• High sensitivity on dust particles of 0.3 μm or greater
• Based on laser light scattering technology, readings are accurate, stable, and consistent
• Low noise and ultra-low power consumption
