Design Of The Air Quality Monitoring System Based On Wireless Sensor Network

Environmental monitoring is the premise of environmental protection and management,only with true,concrete and comprehensive understanding to the state of environmental pollution,will it be possible to develop timely and effective prevention and control measures.Air quality monitoring work can provide air quality data to people in a timely manner,quantify the extent of air pollution,forecast changing in the air quality trends,prevent of serious pollution incidents.Setting up high-quality air quality automatic monitoring system,as well as carrying out the daily air quality and forecast work,it is an effective technology meas to the quantitative and scientific environmental management,it is can provide an accurate basis to the government to made policies and regulations of environmental pollution prevention and control, and can provide strong technical support and security to people's healthy living and normal production,to promote the economic,social and natural environment's coordinated and sustainable development.Setting up air quality monitoring system has great economic and social significance.The system uses wireless sensor networks to collect and send datas, wireless sensor networks are composed of a large number of low-cost micro-sensor nodes which are deployed in the monitoring region,uses wireless communication means to form a multi-hop's self-organizing network,with the aim of perception,collection and processing of perceived target informations in the network coverage region,and send them to observers.This system uses CC2420 wireless module,ATmega128 microprocessors, the air quality sensors,and MC55 GPRS module to build wireless sensor networks,and uses GPRS network to communicate with remote monitoring center,this can achieve the purpuse of air quality monitoring.Monitoring center uses VC.NET programming language,it would not only facilitately made of a friendly interface,but also can easily and efficiently connect and operate with SQL Server database.By test of the system,the system is work normal,and the system can real-timely monitor air quality,reached practical purpose.It is can provide reliable air quality monitoring datas to the environmental protection department.
