While going to check the airborne dust or contamination, it is crucial to know about various things that are certainly making a great way forward to make it sure that, you have rightly check their amount around you and in this way, you can take precautionary steps that are perfect to keep your safe its ill-effects.
While
talking about various sensors that are mainly designed to measure the air
pollution, optical
dust sensor comes
to mind first. These are brilliantly designed to come with right kind of result
and in this way, you can find it easy to make it sure that, you have rightly
make something crucial in this regard.
How
it works?
Optical dust sensor works on the principle of
laser scattering. The air enters through the air inlet where a light source
(Infrared emitting diode) illuminates the particles and the scattered light is
transformed into a signal by a phototransistor. These signals are amplified by
the amplifier circuit and then processed to get the particle concentration. The
intensity of the scattered light depends on the dust particles. More the dust
particles in the air, the greater will be the intensity of light. Apart
from dust sensor, it is also crucial to think about infrared gas sensor that
will easily manage your entire gas issues.
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. A t 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.
