摘要
根据土壤介电测量的通用模型,采用探针式电容传感器,设计了土壤湿度单片机测试系统,阐述了其组成和工作原理,并通过上位机实现自动监测和自动灌溉。实验结果表明:该测试系统具有测量精度高、显示直观、操作方便等特点,可以满足生产实践中的要求。
A device based on the common model of soil dielectric measure theory was designed to measure the soil - moisture. It was mainly made up of a probe capacitance sensor and single chip computer, and communicated with PC through serial device to achieve auto - measuring and auto - irrigation. The result indicated that the device has advantages such as high accuracy, visual display, and convenience. It meets the application of production.
