項(xiàng)目簡(jiǎn)介

1.功能詳解

STM32智能語(yǔ)音臺(tái)燈(機(jī)智云)

功能如下：

STM32F103C8T6單片機(jī)作為主控單元

按鍵切換模式，支持自動(dòng)/手動(dòng)兩種模式

光敏電阻采集光照強(qiáng)度，超聲波傳感器采集坐姿距離，所有參數(shù)顯示在OLED上

智能模式：自動(dòng)識(shí)別有人開(kāi)燈，并根據(jù)環(huán)境光強(qiáng)度控制燈的亮度

按鍵模式：按鍵手動(dòng)調(diào)節(jié)燈亮度

語(yǔ)音模式：通過(guò)語(yǔ)音識(shí)別控制臺(tái)燈調(diào)光與模式切換

坐姿報(bào)警：超聲波距離報(bào)警

機(jī)智云APP：通過(guò)APP可查看數(shù)據(jù)，以及控制下發(fā)
