| 摘 要： | 为充分利用水资源,满足农田灌溉之需,要求旱区农业从粗放的灌溉模式向集约型精量灌溉转变。作物需水状况的准确监测是实现精量灌溉和智能化农业用水管理的前提。基于GSM的土壤湿度监测系统由土壤湿度检测传感器、数据处理模块、GSM无线传输模块3部分组成。该系统采用土壤湿度传感器检测农田中的土壤湿度,单片机通过AD采集湿度信息并与设定值相比较,若湿度低于设定值,则通过GSM模块将信息发至农户,提醒用户开始灌溉。试验表明,该系统能有效监测土壤中湿度,为农户灌溉提供决策依据,实现农作物精量灌溉的远程监测。

| Abstract: | With the growing scarcity of water resources,arid agricultural irrigation mode is required to convert from extensive to intensive precision in order to make full use of water resources to meet the need for more irrigation.Accurate detection of the crop water requirement is the premise of precision irrigation and intelligent management for water usage.In this paper,a soil humidity detecting system is established which consists of soil humidity sensor,data processing module,and GSM wireless transmission module.This system collects data by soil humidity sensor,send data to SOC through A/D,and compares with the set value.If the humidity is below the set value,the system will remind the user to irrigate by sending the warning information through the GSM module.Results shows that the system can moni tor soil humidity effectively,provide data for farmers to irrigate,and realize precision irrigation of crops via remote monitor. |
