摘要

ＰＭ２．５是对人们健康构成威胁的空气污染物之一，要做到针对ＰＭ２．５的有效治理，就要先进行有效的监测，以确定污染物的浓度情况。本论文根据光的米散射原理，设计并组装了基于激光散射原理对空气中ＰＭ２．５浓度进行测量的装置，测量了大气ＰＭ２．５的浓度，应用开源开发平台对系统进来数据处理，并对系统测量准确性进行了评估。

Abstract:

PM2.5 has widely been considered to be an air pollution that threatens the health of the generalpopulation.Any attempts to mitigate PM2.5 would be largely futile without surveillance measurement designedto detect the concentration of PM2.5 particles suspended in the atmosphere.It details the design andconstruction of a device to measure the concentration of PM2.5 particles based on laser-induced Miescattering,and we have conducted experiments to evaluate the accuracy of our system's measurement datausing open-source development platform.

Key words: PM2.5 Mie scattering photoelectric detection module digital collector
