This is a place to show off what went into building my AQI measuring station currently publishing to:
[lpb-air.com](lpb-air.com)
This is a *Minimum Viable Product* and under development. The main purpose is educational.
The webserver is a simple VPS, provisioned with docker-compose.yml.
## aqi_monitor
*aqi_monitor.ino* is the arduino script running on the **nodeMCU ESP8266** microcontroller. The microcontroller posts data to the flask backend on a regular interval.
Connected to that is:
* SDS011: pm2.5 and pm10 sensor from Nova Fitness.
* BME280: Pressure Humidity Temperature Sensor Module.
A [flask](https://pypi.org/project/Flask/) based application that takes the data from the ESP8266 for processing and storage.
[Postgres](https://www.postgresql.org/) handles the storage of the measurements. The data is split up into two different tables, one for aqi related data and one for the weather data.
