PMS5003
Main properties
Zero false alarm rate
Real-time answer
Correct data
Minimum distinguishable particle diameter: 0.3 micrometers
High anti-interference performance due to the patented structure of six sides of shielding
Optional direction of air inlet and outlet in order to adapt the different design
Overview
PMS5003 is a kind of digital and universal particle concentration sensor, which can be used to measure the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. This sensor can be inserted into variable instruments related to the concentration of suspended particles in the air or other environmental enhancement equipments to get correct concentration data in time.
Working principle
Laser scattering principle is for such sensor, i.e. produce scattering by using laser to beam exposure particles in the air, then collect scattering light in a certain degree, and finally get the curve of scattered light change with time. In the end, equivalent particle diameter and the number of particles with different diameters per unit volume can be calculated by microprocessor based on MIE theory.

Overview:
PMSA003 is a digital universal particle sensor based on the principle of laser scattering, which can continuously collect and
Calculate the number of suspended particles of different sizes in the air per unit volume, that is, the particle concentration distribution, and then convert
Become mass concentration, and output in the form of universal digital interface. The sensor can be embedded with various particles suspended in the air
Instrumentation or environmental improvement equipment related to particle concentration provides timely and accurate concentration data.
Working principle:
This sensor uses the principle of laser scattering. Even if the laser is irradiated on the suspended particles in the air to produce scattering,
At the same time, the scattered light is collected at a specific angle to obtain the curve of the intensity of the scattered light over time. Further microprocessing
Based on the algorithm of MIE theory, the equivalent particle size of the particles and the different particle size per unit volume are obtained.
The number of particles.
