Use Optical Dust Sensor To Measure Dust Particle Easily ...

20210818· 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 ...
