基于ARM11的土壤湿度自动控制系统设计
Design of Soil Moisture Automatic Control System Based on ARM11
摘要
Abstract
Since the growth of different crops has different requirements for soil moisture,this paper designed a soil moisture automatic control system with ARM11 as control core,soil moisture sensor as collection module and WIFI module as communication module combined with the feature of the existing greenhouse drip irrigation systems,so as to provide a suitable environment for the growth of greenhouse crops.Through control the solenoid valve connecting with the drip irrigation system,the proposed system could ensure soil moisture remain in an appropriate range,hence realizing the remote monitoring and automatic control of soil moisture in the greenhouse.Besides,greenhouse manager not only could have access to the embedded Boa WEB Server anytime and anywhere to obtain the real-time soil moisture data,but also could inquire the historical data about soil moisture stored in SQLite embedded database.System test results showed that the system proposed could realize the remote monitoring and intelligent control of soil moisture,which was reliable and practical with the soil moisture absolute error of ± 3％.Therefore,the system proposed had certain practicability.关键词
