1、背景

了解博哥的同学都知道，作为一名电子爱好者，博哥除了平时乐于分享基础知识之外，还需要肩负起减轻家庭负担的责任（毕竟从农村走出来的孩子）。

目前，一般加博哥好友的人大概可以分为两类：

学习知识（这一部分目前基本上都很正常运转起来，更多人还是喜欢我的ESP8266开发系列，主要着重点在于基础）
项目开发、毕业设计等（这一部分内容缺失，没有一系列的帖子去记录过博哥有经历过哪些项目开发，不一定是我开发的。。。。）

所以，经过仔细考虑还是需要去介绍一下一些项目开发整理。

2、项目整理

主要分为几个项目：

Home Office
仿生珊瑚
气体传感器
气体采集平台

2.1 Home Office —— 在家办公时调节休息的灯

2.1.1 功能介绍

0、用户A是个设计师，疫情在家工作也常常要加班。大量的工作很容易让他烦躁并且缺乏休息（用户背景）。
1、当时间到达T1(hh1:mm1:ss1)时、表示上班时间到了。随着时间的推移，光线会慢慢变暗（人工拉动窗帘或者遮挡光敏传感器）如果光敏电阻检测到环境暗，则灯环自动亮暖色（环境越暗灯环越亮）。//这里是避免由于忘记开灯，伤害眼睛
2、连续亮了t分钟后，灯变暗变绿色呼吸灯效果， MP3模块播放音乐，提醒用户A休息。
3、只有当人手摸着心率/心跳传感器，检测到稳定（舒畅的状态）时，心跳稳定且平静则恢复1中的暖光，这时重新计时t。//比如像我这种工作狂灯一灭就想立刻重启继续，那就要心跳传感器给予验证，脉搏是OK的才行
4、需要去休息时，点击开关按钮，灯进入休眠（关闭灯），到第二天的T2(hh2:mm2:ss2)再次开启。
5、测试的时候，T1和T2可以设置的间隔短一点，比如5分钟。

2.1.2 实物图片

1、1Arduino nano或uno
2、1DS3231时钟模块（含纽扣电池）
3、1光敏电阻（模块）
4、124位 WS2812LED灯环
5、1无源蜂鸣器/mp3模块
6、1心率传感器/心跳传感器
7、1*9v电池
8、其他可能需要的元器件（面包板、按钮、电阻、电容、导线等）

2.2 仿生珊瑚

2.2.1 功能介绍

在这里插入图片描述

1、用户通过在触控板绘制上图“米”字所示的横线“一”，“|”，“╱”，“╲”这四个的任意一个，来控制圆盘上面的塑料柱。
2、举个例子，当客户绘制“一”后，就从如右上图这排（记为A）开始，往两边扩散形成水波效果。具体的时间就是，A在1s内下去1cm，然后在1s内又复原。在A开始下去的0.3s后，A两边的也开始在1s下去。如此控制，直到最外边的也控制完。
3、当TDS模块采集的值超过250时，圆盘由最中心的点，往外扩散，形成水滴散开的效果。
4、最好是可以支持绘制“～”型图案。

2.3 气体传感器 —— 气体检测

2.3.1 功能介绍

在这里插入图片描述

1、气体芯片的大小约1.5*1.5cm大小，如上图所示，16个圆圈对应16个气体检测通道。气体浓度越大，阻值越大。室内通常情况下就是1M欧姆左右，浓度加大阻值可以去到3M欧姆。
2、每个通道外接一个分压电阻，分压电阻和气体芯片直接连接到ADS1256芯片，每个ADS芯片有8个通道，因此需要两片ADS。ADS是24位精度ADC采集芯片。
3、不需要计算具体的气体浓度值，用电压值的形式表示就行。并显示在HMI显示屏。
4、当然也需要把数据写入SD内存卡。
5、并预留蓝牙接口，把数据也通过蓝牙实时发送出去。
6、通过锂电池供电，并板载锂电池充电电路。

2.3.2 实物图片

1、1ATmega328p
2、4 ADS1115芯片
3、13.5寸HMI显示屏
4、1气体芯片
5、1SD卡
6、16电阻

2.4 气体采集平台

2.4.1 功能介绍

1、CCS811采集CO2的ppm值。
2、MICS6814或4541采集CO、NO2、C2H5OH、H2、NH3、CH4、C3H8、C4H10的ppm值。
3、ppm显示在HMI显示屏。
4、当然也需要把数据写入SD内存卡。
5、并预留蓝牙接口，把数据也通过蓝牙实时发送出去。
6、通过锂电池供电，并板载锂电池充电电路。

2.4.2 实物图片

1、1ATmega328p
2、13.5寸HMI显示屏
3、1CCS811芯片
4、1MICS6814或4541芯片
5、1*SD卡

在这里插入图片描述
