STM32智能语音台灯
（资料分享见文末）
二、项目简介
1.功能详解
基于STM32的智能语音台灯
功能如下：
- STM32F103C8T6单片机系统板作为主控单元
- 按键切换模式，支持智能/按键/远程/语音四种模式
- 光敏电阻采集光照强度，超声波传感器采集坐姿距离，所有参数显示在OLED上
- 智能模式：自动识别有人开灯，并根据环境光强度控制灯的亮度
- 按键模式：按键手动调节灯亮度(三档)，可以按键控制计时
- 远程模式：通过手机蓝牙APP远程控制台灯开关与计时操作
- 语音模式：通过语音识别控制台灯调光与计时功能
- 坐姿报警：超声波距离报警，距离小于10cm提醒坐姿
2.主要器件
- STM32F103C8T6最小系统板
- OLED 屏幕
- 光敏电阻传感器
- 光电红外传感器
- 超声波传感器
- SNR016语音识别模块
- HC-SR04超声波模块
- 大功率LED模块
- 有源蜂鸣器
