Abstract:

In order to measure the dust concentration more effectively in the environment, to facilitate monitoring and improving air quality. Designed a method using optical sensors is proportional to dust concentration is converted to electrical signals, to Sunplus 16bit MCU SPCE061A detection device for the control of the core.This device can smoke concentration, and the unit module and supporting the software design flow chart of the circuit are given. The device can be used to detect the boiler, industrial, automobile exhaust and other sources of dust concentration, both for continuous monitoring.Experiments show that the device shows dust concentration detection accuracy of 01％, stable and high performance.

Key words: dust concentration detection, photoelectric sensors, single chip microcomputer（SCM）
