Dust or small particles of airborne objects are playing vital role to make it sure that, the entire things will be rightly being sum up and will let you know, in which type of environment you are live in. It is essential to know that, the entire things will be rightly mixed up with the help of right kind of things. They are certainly making a great sense that can easily deliver the outstanding result. With optical dust sensor, it is a great idea to monitor the dust that is floating around you.
Before going ahead, it is important to know working principle of optical dust sensor.Based
on the scattering principle of light, the working principle of dust particle
sensor was developed. Particles and molecules scatter light when exposed to
light. At the same time, they absorb some of the energy of the light that hits
them. When a parallel beam of monochromatic light enters the field of the
particle being measured, it will be affected by the scattering and absorption
around the particle, and the light intensity will be weakened.
In this way, the relative attenuation rate of
the incident light passing through the concentration field to be measured can
be obtained. The relative attenuation rate can reflect the relative
concentration of dust in the area to be measured almost linearly. According to
the algorithm and calibration method, the dust concentration can be obtained by
counting the real-time particle number concentration.
In
order to know the presence of the particle around you, it it crucial to get the
best idea to make it sure that, how does the particle
sensor work in order to get all these things according to your own
perception.
