| Abstract: | A design including both hardware and software is developed for a kind of intelligent laser dust test system. It specifies the principle and application of the laser sensor, signal non-linearization processing of sensor and the scheme of digital filtering . The system measured the dust relative density outside the physical experiment center of Suzhou University for 36 days. The results were compared with API (converse to the density of PM10), which is forecast by national environmental protection bureau everyday. |
