Environmental Monitoring System with Wireless Mesh Network Based on Embedded System

Abstract

A kind of environmental monitoring system based on wireless mesh network with the core of embedded system ARM9 S3C2410 microprocessor is presented in the paper. The flexible and self-organizing wireless mesh network is used to achieve the real time acquisition and multi-hop wireless communication of parameters of the monitoring atmospheric environment such as SO2, NO2, NO, temperature, humidity and air pressure, etc. The network structure of the system is established, the hardware architecture of the system is designed, and the system working procedures is given. The entire monitoring system can be quickly arranged and rapidly withdrew without support of base station and has a strong self-healing capability and network robustness and can be used for a variety of occasional atmospheric environmental monitoring.
