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.

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 relative products and applications.

Features:

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

Applications:
