摘要
传感器节点是组成无线传感器网络的基本单位。本文通过对传感器硬件节点的研究,设计了CC2420与ATm ega128单片机的硬件接口,分析了系统组成和原理,重点阐述了节点的硬件设计。本设计遵循了节点的标准化、微型化、低功耗和扩展性等原则。对该节点的测试表明,该方案较好地实现了上述目标。
Sensor node is the basic unit of wireless sensor network. After the research work on the requirement of wireless sensor network node, we design the hardware interface between CC2420 and MCU Atmega128. After the analysis of system operation principle, the hardware design of WSNs node is expounded in detail. The design follows the principle of standardization, miniature low energy consumption and expansibility. Test of the node shows that the implementation achieves the goal preferably.
