Study Of Air Quality Monitoring System Based On ARM

Human society is currently in a period of rapid development,so the environmental problems caused by air pollution problems,especially by the people of concern.A variety of air pollutants for people's health and daily life has a very bad influence,especially in the air PM2.5,PM10,CO and N02 and other pollutants.At present,people's living standards have been greatly improved,and thus the air quality of the situation put forward higher requirements.In order to facilitate the monitoring of air quality and to support data on air pollution control,it is necessary to monitor the various pollutants in the air in real time and effectively.However,air quality monitoring devices currently available in the market or are being used are of high cost,flexibility,poor mobility,and high operational requirements.This design uses ARM embedded technology,the design of an air quality monitoring system.This design choice Raspberry Pi as a development platform,use the ARM Cortex-A53 series BCM2837 as a microcontroller.Based on the Linux Raspbian operating system as the embedded operating system,based on Raspbian developed a variety of data acquisition program,in order to achieve the PM2.5,PM 10,CO,N02,temperature and pressure parameters such as real-time monitoring.The monitoring system is divided into three parts,namely data acquisition module,data processing module and data display module.Three parts can be completed separately for the various functions required to form a complete system.The system uses three kinds of sensors to form the data acquisition module,and use Raspberry Pi as the data processing module,but also through the Yeelink platform to achieve the function of remote monitoring.After testing the entire device,the results show that the parameters of the results are shown to be normal,the system is more stable.This design of the ARM-based air quality monitoring system can be more widely promoted and applied.
