Introduction
MD201 laser dust sensor is a digital universal particle concentration sensor, which can be used to obtain the number and mass of suspended particles in the air per unit volume, ie the particle concentration, and output in the form of digital interface.
The sensor can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particles in the air to provide timely and accurate concentration data.
The sensor uses the principle of laser scattering, that is, the laser is irradiated on the suspended particles in the air to generate scattering, and at the same time, the scattered light is collected at a specific angle to obtain the curve of the scattered light intensity with time. Then the microprocessor uses Mie ) Theoretical algorithm to obtain the equivalent particle size of particles and the number of particles with different particle sizes per unit volume.Feature
