With the fast development of embedded computing, sensors and wireless communication, wireless sen- sor network (WSN) has been widely used in the environmental supervision, military defense and industrial and agricultural control, which has become a hotspot in the development of electronics and information. CC2430 is a chip solution for ZigBee-based WSN, whose features such as low power consumption, high reliability, and easy networking. Based on CC2430 and ZigBee protocol, an acquisition system for temperature and hu-midity data was designed, which presented the software algorithm for coordinator and ordinary nodes. The test under an interference circumstance indicates that it is of stronger robustness and self-organization.%随着嵌入式计算、传感器、无线通信等技术的飞速发展,无线传感网被广泛应用于环境监测、军事国防和工农业控制等诸多领域,已成为电子信息技术发展的一个热点.CC2430是TI公司针对ZigBee的无线传感网芯片解决方案,具有功耗低,可靠性高,组网简单等优势.基于CC2430和ZigBee协议,设计了温湿度数据采集系统,分别给出了协调器和普通节点的软件算法,在干扰环境下测试表明,网络具有较强的鲁棒性和自组能力.
