Traditional soilless culture management mostly relies on manual inspection and empirical adjustment, which has problems such as delayed parameter control, unbalanced nutrient solution ratio, and resource waste, making it difficult to meet the strict requirements of refined cultivation.The small-sized soilless culture automatic control system based on the STM32F103C8T6 microcontroller integrates a DS18B20 temperature sensor, a PH4502C monitoring module, a YW_J water level monitoring module, a 5516 light detection module, an OLED display, and buttons, realizing real-time monitoring, intelligent regulation, and status display of the cultivation environment. The core functions of the system include: monitoring the ambient temperature through the DS18B20, turning on the ventilation relay and triggering an audible and visual alarm when the temperature exceeds the limit; detecting the pH value of the nutrient solution by means of the PH4502C, automatically adding water or nutrient solution when the pH value is out of range, and activating the audible and visual alarm at the same time; using the YW_J to monitor the water level of the water tank, automatically replenishing water when the level is below the minimum value, and triggering the audible and visual alarm when it is above the maximum value; detecting the light intensity through the 5516 module, turning on the fluorescent lamp when the intensity is lower than the set value, and turning it off when it is higher than the set value; supporting on-site setting of various parameter thresholds through buttons; and displaying all monitoring data in real-time via the OLED display.The implementation of this system has effectively improved the automation and precision level of small-sized soilless culture management. Through multi-parameter collaborative monitoring, intelligent regulation, and status visualization, it provides a stable and suitable environment for crop growth. At the same time, it offers a reference for the upgrading of cultivation equipment in families and small farms, and has high practical value and promotion significance.Keywords:soilless culture; STM32; automatic control; environmental monitoring; intelligent regulation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 温度检测模块选择2.1.3 PH 值检测模块选择2.1.4 水位监测模块选择2.1.5 光照检测模块选择2.1.6 显示模块选择2.1.7 按键模块选择2.1.8 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 温度检测模块电路3.3 PH 值检测模块电路3.4 水位监测模块电路3.5 光照检测模块电路3.6 显示模块电路3.7 按键模块电路3.8 声光报警模块电路3.9 继电器控制模块电路第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 ADC模数转换子流程设计第 5 章 实物测试5.1 整体实物测试5.2 温度检测与通风控制功能测试5.3 PH 值检测与水肥调节功能测试5.4 水位检测与补水控制功能测试5.5 光照检测与补光控制功能测试5.6 按键设置与显示功能测试5.7 声光报警功能综合测试第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
