摘要
在光学散射消光原理基础上,采用双波长的方法实现了可吸入颗粒物浓度的精确测量。并以单片机为核心实现了对颗粒浓度的采样、计算;通过3G网络实现数据的传输和共享。实验表明检测仪具有良好的性能。
A precision measurement for the concentration of inhalable particulate matters was investigated using optical scattering extinction and double wavelength method .The sampling and calculation of PM was realized by the microcontroller unit who was treated as the core ,and could be transmitted and shared by third-Generation (3G) .The experiment indicates the detector has good performance .
