本毕业设计旨在设计一种智能远程浇花系统，通过STC89C52单片机和多种传感器实现对植物生长环境的实时监测与控制。系统采用土壤湿度模块检测土壤湿度，当湿度低于设定最小值时，触发声光报警，并通过GSM模块向主人发送浇水请求短信，等待主人回复决定是否启动浇水。同时，系统还通过液位传感器检测蓄水池液位，当液位低于设定最小值时，触发声光报警，并通过GSM模块向主人发送加水请求短信，等待主人回复决定是否启动加水。在蓄水池加水期间，即使土壤湿度低于设定最小值，也不进行浇水，确保蓄水池加水完成后再进行浇水。系统具备按键设置各项阈值的功能，并通过LCD1602显示屏实时展示监测数据，方便用户了解植物生长环境状况。

This thesis aims to design an intelligent remote plant watering system using the STC89C52 microcontroller and various sensors to achieve real-time monitoring and control of the plant growth environment. The system employs a soil moisture module to detect soil humidity, and when the humidity falls below the predefined minimum value, it triggers a sound and light alarm. Additionally, the system sends a watering request message to the owner’s mobile phone through the GSM module, waiting for their response to decide whether to initiate watering. Furthermore, the system utilizes a liquid level sensor to monitor the water level in the reservoir. If the level drops below the set minimum value, it activates a sound and light alarm and sends a water refill request message to the owner. Similar to the watering scenario, the system waits for the owner’s response before initiating the water refill process. During the water refill period, even if the soil humidity is below the minimum value, no watering will take place, ensuring that watering occurs only after the reservoir has been refilled. The system is equipped with buttons to adjust various threshold values and utilizes an LCD1602 display screen to provide real-time monitoring data, facilitating the user’s understanding of the plant growth environment.
Keywords: Intelligent remote plant watering; Soil moisture detection; Liquid level sensor; GSM module; Sound and light alarm.
