摘要
随着人们对居住环境舒适度和健康防护需求的提升,便捷、智能的驱蚊设备成为日常生活中的重要需求。传统电热蚊香器多依赖人工操作,存在余量监测不及时、无法精准定时控制以及远程管理缺失等问题,不仅影响使用体验,还可能因溶液耗尽仍持续工作造成能源浪费。因此,研发一款具备自动监测、定时控制、远程管理功能的智能电热蚊香器具有重要现实意义。
本设计提出一种基于 STM32F103C8T6 单片机的智能电热蚊香器。系统核心功能包括:通过 YW-01D 液位传感器实时检测电蚊香溶液余量,当检测值低于用户设定的最小值时,自动控制继电器关闭电蚊香;依托单片机内部时钟实现定时开启或关闭电蚊香的功能,同时联动 CN-TTS 模块进行 “电热蚊香已打开”“电热蚊香已关闭” 的语音播报提醒;借助 ESP8266-12F WiFi 模块,支持用户通过手机端远程控制电蚊香开关,并实时接收设备传输的工作状态、余量等检测数据;在电蚊香工作期间,精准控制雾化片运行以实现蚊香液气化;通过 OLED 液晶显示模块清晰展示设备使用时长与当前工作状态;此外,用户可通过按键自主设置电蚊香溶液的最小阈值,满足个性化使用需求。
该智能电热蚊香器为用户提供了高效、便捷的驱蚊解决方案,通过自动监测与智能控制避免能源浪费,远程管理功能提升使用灵活性,语音播报与显示功能增强交互体验,有效保障驱蚊效果的同时,进一步提升了生活的便捷性与舒适度。

Design of Electronic Blood Pressure Monitor Based on Single Chip Microcomputer
Abstract
With the improvement of living standards and the enhancement of health awareness, monitoring blood pressure and heart rate has become an important part of people’s attention to their own health. For middle-aged and elderly people, abnormal fluctuations in blood pressure and heart rate, if not monitored and treated in a timely manner, may lead to serious health problems and even endanger their lives. Therefore, it is necessary to develop a device that can conveniently and accurately monitor blood pressure and heart rate.
This design proposes an electronic blood pressure monitor based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the current user’s diastolic and systolic blood pressure through the blood pressure detection module; Using a heart rate detection module to measure the current user’s heart rate; The user initiates the measurement by pressing a button; When abnormal heart rate or blood pressure is detected, the system will sound and light an alarm; Display measurement values through OLED; At the same time, the system stores the detected blood pressure through a storage module, which can hold up to 20 sets, and users can view them by pressing a button.
The function of this electronic blood pressure monitor is to provide people with a convenient and effective tool for monitoring blood pressure and heart rate. By timely monitoring and alerting, it can help people detect health hazards as early as possible, facilitate timely measures, ensure physical health, and improve quality of life.
