摘　　要：土壤水分快速、准确的测量是精细农业中需要解决的关键技术。为了实现土壤水分的实时测量,设计一种水分快速测量仪是十分必要的。为此,在研究用于测量水分的光谱技术基础上,提出了一种基于MSP430F149单片机为核心的土壤水分测量方案,详细地阐明了土壤水分测量仪的软硬件和抗干扰设计。由于该测量仪具有体积小、低功耗、实时性好等特点,有利于进行野外实时测量。The rapid and accurate soil moisture test is a key technique to be solved in precision agriculture. It is necessary to develop a rapid soil moisture measurement instrument in order to realize soil moisture real-time measurement. On the basis of researching measure moisture relaying on spectral bands, this paper presents a kind of design method based on MSP430F149 single chip microcomputer, and describes the design of hardware, software and anti-interference of a soil moisture measurement instrument. This kind of sensor and the system composition of moisture content detector. Its characteristics of small volume, low-power consumption and good real-time make it convenient for field measurement.
