为提高灌溉的精确度与精细化种植的用水效率，研究设计了一种基于 Raspberry 的精准灌溉系统。采用Raspberry Pi 3b与相关传感器设计了系统的硬件，应用pyhton语言编写系统相关程序，并搭建数据库，编写了二维模糊控制器的模糊算法控制程序，其输入量为土壤湿度和土壤湿度的变化值，输出量为直流电机的 PWM 值。最后通过黄瓜幼苗的种植进行试验，达到了预期的节水目标。为智能灌溉的全面实现提供理论基础与参考依据。
Abstract
In order to improve irrigation accuracy and water use efficiency of fine planting, a precise irrigation system based on Raspberry was designed. The hardware of the system is designed with Raspberry Pi 3b and related sensors. The relevant program of the system is written in pyhton language, and the database is built. The fuzzy algorithm control program of the two-dimensional fuzzy controller is compiled. The input value is the change value of soil moisture and soil moisture, and the output value is the PWM value of the DC motor. Finally, through the experiment of Cucumber Seedling planting, the anticipated goal of water saving was achieved. It provides theoretical basis and reference basis for the full realization of intelligent irrigation.
