# Air Quality Station

This is the project for ESP32 C6 board with 1,47 LCD display from Waveshare.

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

## CO2

`SDC41` CO2 sensor (generic from Ali) [Official link](https://sensirion.com/products/catalog/SCD41)

## Temperature, humidity, pressure

`BME680` Generic sensor from Ali [ESPHome doc](https://esphome.io/components/sensor/bme680.html)

## Display

Test: simple I2C display monochromatic.

# Etc

Some other stuff for battery power and casing is needed.

# Help
