PM sensor description The working principle of the RS-PM-*-2-EX industrial pm2.5 pm10 sensor is: using the principle of laser scattering measurement, and the scientific and unique algorithm calculates the particle mass concentration of the equivalent particle size per unit volume. This PM2.5&PM10...
To implement such systems, we first assess the accuracy of low-cost dust sensors and identify the most reliable sensor through a comprehensive set of evaluations. We also investigate the inner working principle of the selected sensor. By conducting a set of lab-scale controlled experiments, we ...

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.Different from the pumping dust detection sensor, the HM-3301 innovatively uses fan blades to drive air, and the air ...
The working principle of The sensor adopts laser scattering principle, if laser scattering produces on the suspended particles in the air, at the same time collecting light output at a specific Angle, to get the curve of the scattering light changes over time, and then the theory of using mic...
This sensor works on the principle of laser scattering. The sensor has a fan which creates a controlled airflow so the environmental particulates pass through a focused laser beam. The particulates cause light scattering which is detected by a photodiode and then converted into PM con...
Working Principle The HM-3301 Dust Sensor is based on the advanced Mie scattering theory. When light passes through particles with quantity same as or larger than wavelength of the light, it will produce light scattering. The scattered light is concentrated to a highly sensitive photodiode, ...
The samplings in all three locations were made by the same type of sampling sensor—Nova Fitness “SDS 011”. The sensors use the laser-scattering principle (Wriedt, 2012). The declared operating range is 0 to 999.9 μg/m3 and the manufacturer claims a relative error of 15% and 10 μg...
Working principle Laser scattering principle is used for such sensor, i.e. produce scattering by using laser to radiate suspending particles in the air, then collect scattering light in a certain degree, and finally obtain the curve of scattering light change with time. In the end, equivalent ...
