摘要
当前,智能化技术不断发展,为了提升现代农田的智能化管理水平,设计以NodeMCU(节点微控制单元)作为中央控制器的智能浇灌系统,实现农田灌溉智能化.YL-69 土壤湿度传感器用于检测土壤含水量,DHT11温湿度传感器用于检测环境温度和湿度,中央控制器负责数据的采集与处理,通过内置的ESP8266芯片连接Wi-Fi将数据无线传输至网页端进行实时监测与控制,并对比系统设置的阈值指标,反馈至微控制器,微控制器通过控制继电器打开水泵对土地浇灌,并且搭建数据库进行数据记录与分析.该系统结构简单,可靠性较高,可实现浇灌的无人化管理,具有重要的现实意义.
Abstract
At present,with the continuous development of intelligent technology,in order to improve the intelligent management level of modern farmland,an intelligent irrigation system with NodeMCU(Node Mi-cro Control Unit)as the central controller is designed to realize intelligent farmland irrigation.YL-69 soil moisture sensor is used to detect soil water content,DHT11 temperature and humidity sensor is used to de-tect ambient temperature and humidity,while the central controller is responsible for data collection and processing.Besdies,the built-in ESP8266 chip is connected to WIFI to wirelessly transmit the data to the web page to conduct real-time monitoring and control,and compare the threshold indicators set by the sys-tem,feedback to the microcontroller,the microcontroller turns on the water pump through the control relay to irrigate the land,and builds a database for data recording and analysis.The system has simple structure and high reliability,and can realize unmanned management of watering,which has important practical sig-nificance.
