【摘要】 为了实现蔬菜大棚的科学管理,设计了一种以ESP32主控芯片为核心的环境数据采集及上传系统。系统能够对大棚环境进行实时监控,ESP32自带无线通信模块可以连接指定Wi-Fi网络,收集温湿度、光照传感器的环境数据并通过MQTT协议上传到阿里云物联网平台,同时环境数据也会显示在板载的液晶显示屏上,方便现场和远程查看信息。系统所用芯片集成Wi-Fi通信模块使得系统简化可降低成本,能够准确地实时监测当前环境数据,实现了设计需求。更多还原

【Abstract】 In order to realize the scientific management of vegetable greenhouse,an environmental data obtaining and uploading system based on the main control chip ESP32 is designed in this paper.The system can monitor the environment of the greenhouse in real time.The ESP32 comes with a wireless communication module that can connect to a designated WiFi network,collect environmental data from temperature,humidity,and light sensors and upload it to the Ali Internet of Things platform through the MQTT protocol.At the same time,the environment data can be displayed on the onboard LCD screen,it is convenient for viewing information on site and remotely.The chip used in this system integrates a Wi-Fi communication module to simplify the system and reduce costs,and it can accurately monitor current environmental data in real time,fulfilling the design requirements.更多还原
