Traditional agricultural and forestry irrigation methods mostly rely on manual experience judgment, which have problems such as inaccurate irrigation timing, serious waste of water resources, and high labor intensity, making it difficult to meet the large-scale and refined needs of modern agricultural and forestry production.The photovoltaic agricultural and forestry humidity detection and irrigation system based on the STM32F103C8T6 microcontroller integrates DS18B20 temperature sensor, YL69 soil moisture sensor, solar power supply module, voltage monitoring module, buttons, OLED displays, ESP8266WiFi module and irrigation execution equipment, realizing automatic monitoring of agricultural and forestry environment and intelligent irrigation control. The core functions of the system include: real-time monitoring of ambient temperature through DS18B20 to provide environmental reference for irrigation decisions; detecting soil moisture through YL69, automatically starting irrigation equipment when the humidity is lower than the preset minimum value, and turning off irrigation when it is higher than the maximum value to achieve precise water replenishment; using solar energy to supply power to the battery, and then the battery supplies power to the system, taking into account environmental protection and battery life; real-time monitoring of the output voltage of the solar panel through the voltage monitoring module, triggering an audible and visual alarm when the voltage is lower than the minimum value to remind maintenance; supporting the setting of temperature, humidity, voltage and other parameter thresholds through buttons, as well as manual control of irrigation switches and mode switching; real-time display of monitoring data, set thresholds and system operation modes through 3 independent OLED displays; uploading data to Alibaba Cloud platform with the help of ESP8266WiFi module, supporting mobile phone remote viewing of data, setting parameters and controlling irrigation equipment.The implementation of this system effectively improves the automation and intelligence level of agricultural and forestry irrigation, reduces manual intervention, improves the efficiency of water resources utilization, provides an efficient and reliable solution for large-scale agricultural and forestry production, and also provides a reference for the research and development of similar photovoltaic agricultural and forestry measurement and control equipment, with high practical application value.Keywords:STM32F103C8T6; Photovoltaic agriculture and forestry; Humidity detection; Automatic irrigation; WiFi communication; Alibaba Cloud目录第 1 章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 温度传感器选择2.1.3 土壤湿度传感器选择2.1.4 按键模块选择2.1.5 显示模块选择2.1.6 WiFi 模块选择2.1.7 声光报警模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 温度传感器电路3.3 土壤湿度传感器电路3.4 显示模块电路3.5 按键模块电路3.6 WiFi 模块电路3.7 声光报警模块电路3.8 灌溉设备驱动电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 OLED显示流程设计4.5 温度检测模块子流程4.6 WiFi模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 温度传感器功能测试5.3 土壤湿度传感器功能测试5.4 电压监测与太阳能供电模块功能测试5.5 显示模块功能测试5.6 按键模块功能测试5.7 WiFi 模块功能测试5.8 声光报警模块功能测试第 6 章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
