    รายละเอียด

    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 the 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.


     

    Hardware overview:

     

    Working Principle

    The HM-3301 Dust Sensor is based on the advanced Mie scattering theory. When light passes through particles with a quantity same as or larger than the wavelength of the light, it will produce light scattering. The scattered light is concentrated to a highly sensitive photodiode, which is then amplified and analyzed by a circuit. With a specific mathematical model and algorithm, the count concentration and mass concentration of the dust particles are obtained.

    The HM-3301 dust sensor is composed of main components such as a fan, an infrared laser source, a condensing mirror, a photosensitive tube, a signal amplifying circuit, and a signal sorting circuit.
