AirTHD

——基于ESP32的微型空气质量检测仪

关于该项目

用于毕业设计,以及用来解决个人检测二氧化碳浓度的需求的一个项目

采用ESP-IDF框架开发(Arduino里的代码仅有获取传感器数据并显示)

主要功能:获取空气质量数据并输出


项目文件说明

  • Hardware:用Altium Designer设计PCB
  • Fireware:主要固件在ESP-IDF里,Arduino只做了传感器获取和显示功能
  • Software:目前仅有一个手机APP,用于读取蓝牙广播数据并计算相应物理量
  • 3DModel:外壳3D打印文件
  • Docs:相关资料

关于硬件方案

已验证,焊接能力不强建议钢网铁板烧

板载SHT30部分电路仅为个人MCU测温使用可以不焊,实际使用需直接买SHT30模块叠在SGP30上方

动手能力强的可以自行添加电池及无线充电,外壳有空间(可改外壳自行适配电池)放电池和无线充电模块


功能列表:

  • 获取传感器数据:SHT30中的温湿度与SGP30中的TVOC值及二氧化碳浓度

  • 连接WIFI获取B站粉丝数室外温度天气类型

  • 屏幕显示通过LVGL展示上述的数据

  • 串口输出(波特率115200)

  • 蓝牙BLE广播传感器数据(Major与Minor值)

    ​ 如Major = 30625即为温度30.6度,湿度25%

    ​ 如Minor = 14512即为eCO2=1450ppm,TVOC=1200ppb

    ​ 注:eCO2维持在800ppm以下一般不用开窗通风


还有一个简单的安卓APP

其他的后续再补充,有用的话记得点星星~
