The Grove - Laser PM2.5 Sensor (HM3301) is a new generation of laser dust detection sensors. It 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.
This module is a perfect choice for dust detectors, intelligent air purifiers, intelligent air conditioners, intelligent ventilation fans, air quality testing, haze meters, environmental monitoring, and related products and applications.
- 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
