Design Of Wireless Sensor Network Nodes For Environment Monitoring

Wireless Sensor Network (WSN) is a hot research subject in sensor technology area recent years, which is widely used in many fields as a new information technology of acquisition and processing. It is a certain network planning model in the specific context, which is consisted of a collection of sensor nodes. Sensor node is a micro-computer system. It is specifically designed for wireless sensor networks. It plays an important role in the whole network.In this paper, to environmental monitoring as the background, designed a wireless sensor network node. It achieves the main jobs:(1)The dissertation carried out a sound study on the development,Present status,some key technique,as well as the basic Principles and Philosophy of WSN.(2)In this dissertation, a new kind design of sensor node based on CC2431, which can be used in environment monitoring is proposed after analyzing the structure of sensor node. Its hardware design mainly includes modules of CC2431 and sensor; TinyOS is used in software system, and its transplant technique is introduced and analyzed.(3)The work also studied the technology of environment monitoring in coal WSN, and a monitoring system is build for monitoring the environment information of humidity in coal mine.Wireless sensor network nodes for environment monitoring has been developed and is proven that the node is designed to meet the down-hole monitoring of various environmental parameters, and achieved good results.
