当前无线传感器网络技术逐渐成熟，促进了智能农业和精准农业的发展。为获得实地、大范围和实时的农田信息，提出了一种基于ZigBee 技术的信息监测系统设计方案，包括硬件平台的设计和系统软件的开发。硬件平台以ATmega 128单片机和CC 1101射频芯片为核心，主要由数据处理单元、无线模块、传感器控制矩阵、数据存储、供电单元、模拟接口和数字接口等构成。在TinyOS 操作系统的开发平台上利用 nesC 语言实现了传感器节点和汇聚节点的软件开发。对传感器节点主要进行了传感器驱动程序设计，而汇聚节点主要进行了串口通信编程。此外，根据节点不同的工作模式，设计了节点的节能算法。该系统稳定、可靠，满足设计需求。
