Use Optical Dust Sensor To Measure Dust Particle Easily

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.

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. You can also use methane gas sensor to make it sure that, you have rightly made all your effort to test the quality and variables of the methane gas.
