二、项目功能简介
【开源】STM32单片机智能万年历/智能闹钟设计（代码+原理图+仿真）-编号：CY26040
【功能介绍】
（1）实时时钟显示：DS1302时钟模块实时显示当前时间，确保时间信息清晰直观
（2）时间设置与断电保存：可灵活调整时间设置，系统具备断电记忆功能，重启后仍能保持最新时间配置
（3）闹钟设置与蜂鸣器报警：支持自定义闹钟时间（2个），到达设定时间后蜂鸣器自动鸣响提醒，并可手动关闭
（4）环境采集与显示：实时监测环境温湿度、光照数据并显示，如检测到数值异常，系统将自动触发声光报警
（5）手机APP功能：可通过手机APP同步网络时间，自动校准设备时间；支持远程设置闹钟，并可在APP端灵活开启或关闭闹钟功能
