Abstract

Abstract

An aerosol concentration measurement method based on two channels of transmission and scattering was proposed and a detection device was designed in this paper. The intensities of light scattering at the 90 and transmitting light were measured by two detection ways in periodic, which eliminates the inaccuracy because of light source aging and the difference of detector sensitivity. By choosing MSP430 to be the controller, optical signals were modulated by an exerting pulse signal to LD, and the signals detected were amplified and filtered in the receiver. The system can effectively eliminate environmental interference with the measurement results. The experiment results show that the linear correlation coefficient of the system is 0.976 5 with good linearity, and it is operated stably and reliably.
