摘要
在家庭植物工厂种植中，光照、温度、病虫害及水质酸碱度等环境因素的适宜与否，直接影响植物的生长状态和品质。传统的家庭植物管理主要依赖人工观察和手动调节，不仅耗费时间和精力，且难以精准把控各项环境参数，易因调控不及时或不准确导致植物生长不良，无法满足家庭种植者对高效、便捷管理植物的需求。
基于 STM32F103C8T6 单片机的家庭植物工厂控制系统，整合了 5516 光照检测模块、DS18B20 温度传感器、HC-SR04 超声波检测模块、PH4502C PH 检测模块、3 个独立按键、OLED 显示屏、ESP8266WiFi 模块及执行设备（补光灯、加热装置、制冷装置、通风设备、紫色诱杀灯、循环水泵等），实现了家庭植物工厂环境的自动化监测与智能调控。系统核心功能包括：通过 5516 光照检测模块监测光照，光照较低时自动开启补光灯；通过 DS18B20 检测温度，温度小于最小值时自动打开加热装置，温度大于最大值时自动启动制冷和通风设备；通过 HC-SR04 超声波检测模块检测是否有虫子，检测到虫子时打开紫色诱杀灯进行诱杀；通过 PH4502C PH 检测模块检测水中 PH 值，PH 值超出阈值范围时自动打开循环水泵；支持通过 3 个独立按键设置各参数阈值，控制补光灯、加热、制冷、诱杀灯及循环水泵；通过 OLED 显示屏实时显示各项监测数据及设备状态；利用 ESP8266WiFi 模块将数据上传至手机端，手机端可设置阈值并控制相关设备。
该系统的实现，有效提升了家庭植物工厂管理的自动化与智能化水平，减少了人工干预，确保了植物生长环境的稳定适宜，为家庭种植者提供了高效、便捷的解决方案，同时为同类家庭种植控制系统的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
In home plant factory cultivation, the suitability of environmental factors such as light, temperature, pests and diseases, and water pH directly affects the growth status and quality of plants. Traditional home plant management mainly relies on manual observation and manual adjustment, which not only consumes time and energy but also makes it difficult to accurately control various environmental parameters. It is easy to cause poor plant growth due to untimely or inaccurate regulation, failing to meet the needs of home growers for efficient and convenient plant management.
The home plant factory control system based on the STM32F103C8T6 microcontroller integrates 5516 light detection modules, DS18B20 temperature sensors, HC-SR04 ultrasonic detection modules, PH4502C PH detection modules, 3 independent buttons, OLED displays, ESP8266WiFi modules, and executive devices (fill lights, heating devices, refrigeration devices, ventilation equipment, purple trapping lights, circulating water pumps, etc.), realizing automatic monitoring and intelligent regulation of the home plant factory environment. The core functions of the system include: monitoring light through the 5516 light detection module, automatically turning on the fill light when the light is low; detecting temperature through DS18B20, automatically turning on the heating device when the temperature is lower than the minimum value, and automatically starting the refrigeration and ventilation equipment when the temperature is higher than the maximum value; detecting whether there are insects through the HC-SR04 ultrasonic detection module, and turning on the purple trapping light to trap and kill insects when detected; detecting the pH value of water through the PH4502C PH detection module, and automatically turning on the circulating water pump when the pH value exceeds the threshold range; supporting the setting of various parameter thresholds through 3 independent buttons to control the fill light, heating, refrigeration, trapping light and circulating water pump; real-time display of various monitoring data and equipment status through the OLED display; uploading data to the mobile phone through the ESP8266WiFi module, and the mobile phone can set thresholds and control related equipment.
The implementation of this system effectively improves the automation and intelligence level of home plant factory management, reduces manual intervention, ensures a stable and suitable growth environment for plants, provides an efficient and convenient solution for home growers, and also offers a reference for the research and development of similar home planting control systems, with high practical application value.
