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。
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 Micro 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 detect 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 system,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 significance.
