Title   Setting of dust concentration          detection device based on ARM MCU

Abstract

China's wanton development, so that environmental problems are becoming more and more serious. Smoke and dust on the air caused by air pollution is more attention, especially the PM2.5 put forward, so that people have a sense of prevention of air pollution.

In this paper, the dust concentration test system based on ARM single chip microcomputer is introduced. The design idea of dust collection device is expounded, and the design process of hardware and software of the system are explained in detail. The design uses STM32 as the main control device, using GP2Y1010AU as dust sensor, with four digital tube as the display device, and through the physical experiment, to obtain the corresponding experimental data. GP2Y1010AU can directly read the dust concentration data, data conversion, read dust information and transmission simulation model to say STM32 development board. Four bit digital tube is the most simple display, can display the dust concentration in real time. In the design uses the monolithic computer commonly used C language to carry on the procedure to prepare. Download and debug software by MDK Keil. And through the physical testing of the dust concentration of the environment, to obtain the relevant data. Has a very good practical value.
