Skills I learned during this project:
|
|
- Setup the minimal Raspbian operating system to the RPi, called Minibian
|
|
- Install and use Python, and the Python virtual environment
|
|
- Install and use Flask, a Python-based web micro-framework
|
|
- Install and use uWSGI as the application server for Flask
|
|
- Install and use Nginx light-weight web server
|
|
- Use Skeleton to make the web UI look better
|
|
- Use the RPi GPIOs as digital input and outputs
|
|
- Use a DHT22 humidity and temperature sensor
|
|
- Install and use the SQLite database to store sensor data
|
|
- Add a cron job to store sensor data every so many minutes
|
|
- Use the Google Chart API to create visual representations of the sensor data
|
|
- Use Javascript/JQuery to add interactivity to web pages
|
|
- Use Plotly for graphical analysis of sensor data
