PM2.5 Air Quality Sensor and Breadboard Adapter Kit – PMS5003

Features:
-PMS5003 is a kind of digital and universal particle concentration sensor,
-which can be used to obtain 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
-improvement equipments to provide correct concentration data in time.
-Working principle
-Laser scattering principle is used for such sensor, i.e. produce scattering by
-using laser to radiate suspending particles in the air, then collect scattering
-light in a certain degree, and finally obtain the curve of scattering light change
-with time. In the end, equivalent particle diameter and the number of particles
-with different diameter per unit volume can be calculated by microprocessor
-based on MIE theory.
