# Air Quality Station for Indoor use only

This is the project for Air Quality Monitoring device.

This device should report following information:

- CO2 ppm measurement

- temperature

- humidity

- atmospheric pressure

- AQI

- staistics

The main functionality:

- save all measurements into the local SD card database

- draw different graphs for each sensor measure history statistics at OLED display

- integrate all sensors in Home Assistant if the device is connected to WiFi and HA is added

- start Wifi in `AP mode` with `captive_portal` modified to show all measures and `js` graphs
