SM-UART-04L Particulate Dust Sensor | Telaire

SM-UART-04L is a laser-based Particulate Dust Sensor that detects dust particle concentration in air by using an optical sensing method. A laser light emitting diode (laser LED) and a photo sensor are optically arranged in the device. The photo sensor detects the reflected laser LED light by dust particles in air. The dust sensor can detect small particles from large house dust, by the pulse pattern of the …

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

18/08/2021· 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 ...

Clean Dust Particles or Smudges From the Surface of the ...

There are two ways to clean dust off the image sensor. You can use the Cleaning Mode in the camera menu to let the sensor shake the dust off. You can also detach the lens and use a hand-held camera cleaning blower to manually blow away any dust particles from the surface of the image sensor. If there are smudges of any kind on the sensor, we recommend that a professional camera shop clean it ...

Operation principle of dust-sensor technology

Our sensor is designed to detect the particles whose size is over micro meter, which means it can detect all circulating dust that that is dangerous for human lungs. This dust can stay in the lungs of human as well it can be breath out. Most of the dust such as tick, spore of mildew are over 1 micro meter. Figure 1 - Model of dust sensor
