Design and implementation of wireless sensor network node in environment monitoring

Abstract

In terms of the demands on environment monitoring, by taking monitoring the area polluted and weather environment as application background, temperature and humidity etc as inspecting parameters, tiny wireless sensor network nodes are designed, the node took the MSP430 ultra low power MCU as the core, and used 2.4G CC2420 RF chip, the solution and implementation of hardware structure of the node were introduced. An experiment for the wireless sensor network nodes communication is made, the experiments results of testing nodes indicate that nodes can gather and process data effectively and communicate successfully between nodes, the technical feasibility of the design are verified by practical testing.
