coal mine dust sensor

Instruction

Dust sensor is made in Japan is used to perceive a daily use of machinery.Can sense that, tobacco smoke and pollen, house dust, etc. More than 1 micron tiny particles.

Principle

Under the irradiation of light particles and molecules will produce light scattering phenomenon, and the same time, also absorb part of the irradiation of light energy.When a beam of parallel monochromatic light incident to the measured particle field, are influenced by the particle scattering and absorption, the light will be attenuation.So the incident light can be obtained by the relative attenuation concentration field under test.And the size of the relative attenuation can basically linear response to relative concentration of dust.The size of the light intensity and the photoelectric convert electrical signal is directly proportional to the strength, through the relative attenuation measured signals can be obtained

Character

Dust sensor can sense that, tobacco smoke and pollen, house dust and so on more than 1 micron tiny particles. Small volume, light weight, easy to install. 5 v input circuit, signal processing. Hidden within the airflow generator, able to attract the external atmosphere. Dust sensor maintenance is simple, can keep the sensor characteristics for a long time.

Application

1, air purifier, and the air is fresh machine;
2, air conditioning;
3, air quality monitoring equipment;
4, air conditioning and other related products.

Reference

The main parameters of dust sensor
1, the optical principle, and can detect more than one micron particle;
2, 5 VDC power supply;
3, detection range of particles: maximum to 8000 PCS / 283 ml (more than 1 um particles
