This project builds a WiFi-based display which can show you the AQI from a PurpleAir air quality sensor.

This project is a work in progress. The code is ugly and not polished. It's kind of a mess. Don't consider this an official release or anything. Really you should just move on and forget you saw this.

Still interested?

Ok, read on.

• Raspberry Pi Pico W
• Waveshare Pico-LCD-1.114
• A PurpleAir air quality sensor
• A 3D printer to print the case (Optional)

The software runs in Micropython. Load the wireless micropython firmware to the Raspberry Pi Pico W board and then use a tool like Thonny to copy all of the files in src over to the Raspberry Pi Pico W board. Make sure you edit settings.py to include the IP address of your PurpleAir sensor, as well as your WiFi SSID and password!
