摘要
随着现代育儿观念的不断升级，对婴儿的实时监护与安全保障成为家庭关注的重点。传统的婴儿监护方式主要依赖家长的人工观察，不仅耗费大量精力，还存在监护不及时、响应滞后等问题，难以满足全天候、精准化的监护需求。
基于 STM32F103C8T6 单片机的婴儿监护系统，整合了 MLX90614 体温传感器、MAX30102 心率检测模块、YS 湿度检测模块、SY 声音检测模块、DFPlayer Mini 音乐播放模块、5516 光照检测模块、SU-03T 语音识别模块、3 个独立按键、OLED 显示屏及 ESP8266WiFi 模块等，实现了对婴儿状态的全方位监测与智能响应。系统核心功能包括：通过 MLX90614 实时监测婴儿体温，异常时及时预警；借助 MAX30102 检测婴儿心率，保障生命体征稳定；利用 YS 湿度检测模块判断婴儿是否尿床，提升护理及时性；通过 SY 声音检测模块识别婴儿哭泣，触发 DFPlayer Mini 音乐播放模块播放音乐安抚；结合 5516 光照检测模块，当环境光照低于最小值时自动打开照明灯；支持 SU-03T 语音识别控制音乐播报；通过 3 个独立按键实现界面切换、阈值设置、音乐启停及照明控制；OLED 显示屏实时显示各项监测数据；ESP8266WiFi 模块将数据传输至手机端，支持手机远程控制音乐播放与照明，且在婴儿体温、心率异常或出现尿床、哭泣情况时，手机端会进行弹窗震动提醒。
该系统的实现，有效提升了婴儿监护的自动化与智能化水平，减轻了家长的监护压力，确保能及时响应婴儿的各种需求与异常状况，为婴儿的健康安全提供了可靠保障，同时为同类婴儿监护设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous upgrading of modern parenting concepts, real-time monitoring and safety guarantee of infants have become the focus of families. Traditional infant monitoring methods mainly rely on parents’ manual observation, which not only consumes a lot of energy but also has problems such as delayed monitoring and slow response, making it difficult to meet the needs of all-weather and precise monitoring.
The infant monitoring system based on the STM32F103C8T6 microcontroller integrates MLX90614 temperature sensor, MAX30102 heart rate detection module, YS humidity detection module, SY sound detection module, DFPlayer Mini music player module, 5516 light detection module, SU-03T voice recognition module, 3 independent buttons, OLED display, ESP8266WiFi module, etc., realizing all-round monitoring and intelligent response to infant status. The core functions of the system include: real-time monitoring of infant’s body temperature through MLX90614, with timely warning in case of abnormality; detecting infant’s heart rate by MAX30102 to ensure stable vital signs; using YS humidity detection module to judge whether the infant wets the bed, improving the timeliness of care; identifying infant’s crying through SY sound detection module, triggering DFPlayer Mini music player module to play music for comfort; combining with 5516 light detection module, automatically turning on the lighting when the ambient light is lower than the minimum value; supporting SU-03T voice recognition to control music broadcasting; realizing interface switching, threshold setting, music start/stop and lighting control through 3 independent buttons; real-time display of various monitoring data on OLED display; ESP8266WiFi module transmits data to the mobile phone, supporting remote control of music playback and lighting via mobile phone, and the mobile phone will give pop-up vibration reminders when the infant has abnormal body temperature, heart rate, bed-wetting or crying.
The implementation of this system effectively improves the automation and intelligence level of infant monitoring, reduces the monitoring pressure of parents, ensures timely response to various needs and abnormal conditions of infants, provides a reliable guarantee for the health and safety of infants, and also provides a reference for the research and development of similar infant monitoring equipment, with high practical application value.
