摘要
随着人们对居住环境舒适度与健康生活需求的提升，夏季驱蚊方式的便捷性、安全性与节能性成为关注焦点。传统蚊香液多依赖人工手动开关，易出现忘记关闭导致药液浪费、夜间忘开影响睡眠的问题；且盲目长时间使用，不仅增加能耗，还可能因室内蚊香液浓度过高带来健康隐患。因此，研发一种能自动、精准控制蚊香液启停的智能设备具有重要实用价值。
本设计提出了一种基于 STM32F103C8T6 单片机的智能蚊香液控制系统。系统主要功能包括：通过 RTC 内部时钟获取实时时间，支持通过按键修正时间及预设蚊香液启停时段；借助 5516 光照检测模块采集环境光照值，仅当光照值低于设定最小值且处于预设启动时段时，才通过继电器开启蚊香液；配备按键支持用户手动切换蚊香液启停状态；通过 OLED 显示屏清晰展示当前时间、单次使用时长及总使用时长；搭载 ESP8266-12F WIFI 模块，可将设备运行数据实时发送至手机端，手机端不仅能获取实时数据，还可远程设置蚊香液启停时段（如 20 点 – 5 点）并控制其开关。
该智能蚊香液控制系统的作用在于，为用户提供一种高效、节能的驱蚊解决方案。通过 “时间 + 光照” 双重条件触发自动控制，避免无效运行造成的药液与能源浪费；结合手动控制与手机远程控制，提升使用灵活性；OLED 显示与数据上传功能，方便用户掌握设备使用情况，助力打造便捷、健康的居住环境。

Intelligent mosquito repellent liquid control system based on single-chip microcomputer
Abstract
With the increasing demand for comfortable living environments and healthy living, the convenience, safety, and energy efficiency of mosquito repellent methods in summer have become the focus of attention. Traditional mosquito repellent liquid relies heavily on manual switching, which can lead to waste of liquid due to forgetting to turn it off and affecting sleep at night; Blindly using it for a long time not only increases energy consumption, but also may pose health hazards due to the high concentration of indoor mosquito repellent liquid. Therefore, developing an intelligent device that can automatically and accurately control the start and stop of mosquito repellent liquid has important practical value.
This design proposes an intelligent mosquito repellent liquid control system based on STM32F103C8T6 microcontroller. The main functions of the system include: obtaining real-time time through the RTC internal clock, supporting time correction through buttons, and preset mosquito repellent start and stop time periods; Using the 5516 light detection module to collect ambient light values, the mosquito repellent liquid is only activated through a relay when the light value is below the set minimum value and within the preset start-up period; Equipped with buttons to support users in manually switching the start and stop status of mosquito repellent liquid; Clear display of current time, single usage duration, and total usage duration through OLED display screen; Equipped with ESP8266-12F WIFI module, the device operation data can be sent in real-time to the mobile phone. The mobile phone can not only obtain real-time data, but also remotely set the start and stop time of mosquito repellent liquid (such as 20:00-5:00) and control its switch.
The function of this intelligent mosquito repellent liquid control system is to provide users with an efficient and energy-saving mosquito repellent solution. By triggering automatic control through the dual conditions of “time+light”, it avoids the waste of medication and energy caused by ineffective operation; Combining manual control with mobile remote control to enhance user flexibility; OLED display and data upload function make it convenient for users to monitor device usage and help create a convenient and healthy living environment.
