一、视频展示

基于单片机的图书馆座位监测系统 -视频分享

二、项目简介

题目：基于单片机的图书馆座位监测系统
主控:STM32
显示:OLED显示屏
DS1302时钟模块
红外光电
红外测温模块
蓝牙模块
红色led+黄色led
声光报警：LED+蜂鸣器
功能：
1、光电负责检测是否有物品在位置上，红外测温负责识别是人体还是其他物品。
2、若为物品占位则开启蜂鸣器报警提醒不得占位。
3、若为人则正常，当人员长时间使用座位时，黄色灯光亮起一分钟以提醒休息。若人员长时间离开座位时，红色灯光亮起，提示工作人员进行清洁。
4、显示屏显示当前座位编号，数据信息。

三、原理图设计

四、PCB硬件设计

五、程序设计
