摘要
无线传感器网络节点数据采集决定于节点上的传感器模块。三轴向加速度传感器MMA7260性能优越,适合作为传感器模块来感知节点的运动情况。在分析了嵌入式操作系统TinyOS的硬件抽象体系结构及其对传感器驱动提出的设计原则的基础上,使用NesC语言实现了基于micaZ平台的MMA7260驱动程序。驱动程序的接口简单,使用方便,并满足传感器节点低功耗的要求。
Sensor data depends on sensor module of wireless sensor network node.MMA7260 is a three axis accelerometer with superior performance.It is suitable to be used to sense information of node's movement.After introducing hardware abstraction architecture (HAA) and general principles about how sensor drivers are organized in TinyOS,the MMA7260 driver is designed to use NesC based on micaZ platform.
