Atmospheric Environmental Monitoring System Based on Wireless Sensor Network

The atmospheric environmental monitoring system based on wireless sensor network is made up of embedded gateway, sensor nodes and monitoring centre. Sensor node is composed of various sensors meeting the standards for environmental monitoring, ATmega16 microcontroller as a core and ZigBee wireless communication module used to send the acquisition data to the embedded gateway which runs Linux operating system in the S3C2440A embedded microprocessor. Atmospheric environmental monitoring center receives the environmental data uploaded by the embedded gateway and stores them in the database designed with Access 2007, and provides the function as data query based on VC.
