基于ZigBee无线传感网络技术节点设计与实现

摘要

The information is collected by sensors, to produce analog voltage signals. The digital signal is obtained through A/D conversion. CC2430 chip is used as core chip instead of traditional sending model with wired style to take charge of data processing and wireless radio frequency. According to the requirement, the solution of the hardware structure and software design is presented, and the power consumption is also taken into consideration.%利用各类传感器采集外界信息，产生模拟电压信号，通过模数转换进而得到数字信号，摒弃传统的有线串口发数模式，用CC2430芯片作为节点的核心芯片，负责数据处理和无线射频工作。根据以上要求给出了系统硬件结构及软件设计方案，并综合考虑到了节点的功耗问题。
