摘要
随着生活节奏的加快和园艺爱好者对植物养护需求的提升，科学合理的浇花方式成为保证植物健康生长的关键。传统人工浇花存在浇水不及时、水量控制不当等问题，易导致植物生长不良，因此，研发一种能智能、高效进行浇花控制的设备具有重要意义。
本设计提出了一种基于 STM32F103C8T6 单片机的自动浇花系统。该系统主要功能包括：通过 DS18B20 温度检测模块检测环境温度，当温度大于最大值时自动浇花，直至土壤湿度大于最大值后停止；借助土壤湿度检测模块监测土壤湿度，当湿度小于最小值时自动浇水，直至湿度大于最大值；通过 DS1302 时钟模块获取时间，支持定时浇水设置，到达设定时间自动启动浇水；用户可通过按键设置温湿度阈值并控制浇水；通过 OLED 显示屏实时显示各类数据；同时，系统通过 WIFI 模块将测量数据发送至手机端，手机端可远程设置阈值并控制水泵开关。
该自动浇花系统的作用在于，为植物养护提供了一种智能、便捷的解决方案。通过精准监测环境参数和自动控制浇水过程，既能避免人工浇花的弊端，又能根据植物需求合理调节水量，保障植物健康生长，为园艺爱好者节省时间和精力。

Automatic Watering System Based on Single Chip Microcomputer
Abstract
With the acceleration of the pace of life and the increasing demand for plant care among gardening enthusiasts, scientific and reasonable watering methods have become the key to ensuring the healthy growth of plants. Traditional artificial watering has problems such as untimely watering and improper water control, which can easily lead to poor plant growth. Therefore, it is of great significance to develop an intelligent and efficient watering control device.
This design proposes an automatic watering system based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the ambient temperature through the DS18B20 temperature detection module, automatically watering flowers when the temperature exceeds the maximum value, and stopping when the soil moisture exceeds the maximum value; Monitor soil moisture with the help of a soil moisture detection module, and automatically water when the moisture is below the minimum value until it exceeds the maximum value; Obtain time through DS1302 clock module, support timed watering setting, and automatically start watering when the set time is reached; Users can set temperature and humidity thresholds and control watering through buttons; Real time display of various data through OLED display screen; At the same time, the system sends measurement data to the mobile phone through the WIFI module, and the mobile phone can remotely set the threshold and control the water pump switch.
The function of this automatic watering system is to provide an intelligent and convenient solution for plant maintenance. By accurately monitoring environmental parameters and automatically controlling the watering process, the drawbacks of manual watering can be avoided, and the water volume can be adjusted reasonably according to the needs of plants, ensuring healthy plant growth and saving time and energy for gardening enthusiasts.
