摘　　要：简要叙述了无线传感器网络的发展史，讨论了传感器节点的功耗、成本、组网方面的属性及要求，概述了传感器节点的传感单元、通信单元、处理单元及供电单元等四大基本功能单元和两个辅助单元，介绍了一些常用电池和几款适合嵌入式节点设计的微控制器和射频器件，阐述了无线传感器网络领域一些挑战性的问题以及传感器节点的能量管理问题。The development history of sensor networks is introduced, and the characteristics and requirements for a sensor node mainly about the energy, cost and networking are discussed. Some commercial off-the-shelf battery Radio Frequency chips and Micro Controller Unit are summarized and the four necessary units and two additional ones of a sensor node are described. The challenge of wireless sensor network technologies is introduced too. Finally the energy management technology which is very crucial to sensor networks is discussed.
