题目：基于ZigBee的土壤含水率检测系统设计
中文摘要
【摘要】在农业、生态环境科学等领域的研究中，常常需要测量土壤的湿度。土壤湿度测量具有被测土地面积大、测量点多、需要观测时间长等特点。传统的测试方法是将传感器插入土层，然后进行读数记录，不仅花费大量的时间和人力，而且由于人为等因素还会造成数据测试不准等问题。本文采用CC2530作为核心控制器件，利用埋入地下的土壤湿度传感器检测土壤的湿度，采用基于ZigBee和WSN的自组网通信技术实现远程数据采集，克服了传统土壤湿度检测的缺点，讨论了系统的硬件电路设计、软件编程和系统调试。该系统综合了Zigbee 无线网络自组网、自行愈合和超低功耗的优点，能实时监测土壤信息，为进一步简化农业和生态环境的研究操作。最终经过测试结果表明，该系统运行稳定，丢包率低，能及时准确的监控土壤信息，并将土壤含水率维持在适合植物生长的最佳含水量的范围之内。

英文摘要
【Abstract】Research in the field of agriculture, ecology and environmental
science, and often need to measure soil moisture. Soil moisture measurement has a of measured land area measurement points, need a long observation time. Traditional testing methods is the sensor into the soil, and then reading the record, not only spend a lot of time and effort, but also due to man-made and other factors can also cause data test allowed and so on. In this paper, CC2530 as the core control device buried in the ground soil moisture sensor detects the moisture content of the soil, the use of remote data acquisition based on ZigBee WSN group network communication technology, to overcome the traditional soil moisture detection disadvantage of the system is discussed in the hardware circuit design, software programming and system debugging. The system combines the ZigBee wireless network from the network self-healing and ultra-low power consumption advantages, real-time monitoring of soil information to further simplify the research operation of agricultural and ecological environment. After the final test results show that the system is stable, low packet loss rate, timely and accurate monitoring soil, and the soil moisture content is maintained within the scope of the optimum moisture content suitable for plant growth.
