单片机浴室报警器程序+电路图PCB文件（DS18B20,IIC,51,AT24C02,蜂鸣器）

1、氧气浓度采集：本设计采用ZE03-O2（工作电压3.7V-9V DC 温度0-50度湿度20%-90%RH）氧气浓度传感器，适用于浴室氧气浓度检测，虽内置温度传感器进行温度补偿，但程序算法上需将采集数据和输出氧气浓度建立线性关系。

2、信息储存：采用AT24C02（掉电记忆，电可擦除）作为外置EEPROM存储用户设置信息（主要用于存储用户设置时间，报警温度和氧气浓度）。

3、报警部分：当任何一项指标超标时都需要声音报警，不同的指标超标光报警要给用户明确的某项指标超标。

4、浴室模型：本课题是基于浴室，采用CAD对模型进行设计与绘制，模型确定为底面面积为0.64平方米高1米的长方体，长方体内部布满泡沫以此来构建封闭、透气性差和保温性强的环境条件。

5、硬件电路：单片机最小系统板、显示电路、电源与复位电路、报警电路、风机驱动板和氧气传感器和温度传感器电路设计与调试。
