How to:

 

The current settings are detecting PM2.5 (Combustion) and PM10 (dust, pollen), and display highly precise alert levels as: BAD, BAAAD, BAAAAAAD, TERRIBLE and the GIF

Air Quality thresholds

  • Make the MakingFaces Python App to Autostart at startup, so you don't need the keyboard, screen, mouse anymore.
  • 3D Printing files:
    • Nose (preferably SLS print)
    • Insert
    • LED surround cover
    • Legs
    • Enclosure
  • Fit the optical fibres into the mount. You can use a 2mm drill bit to clear up. Trim the optical fibres flush.
  • Put the matrix in place and the LED surround to prevent light leaks. Add the legs on each side and fasten everything with the screws.
  • Pass the 2 cables through the holes of each side s of the nose, make a knot to relieve tensions and solder them to the matrix (Power, Ground, Din, Cin)
  • Mount the Pi onto the enclosure. Connect the sensor to the Pi and stick it with double-sided tape.
  • Connect the nose's long cable to the Pi (5v, Ground, SCK, MOSI)
  • Connect the Pi4 USB-C to power the Pi, and close the enclosure with the screws.
  • Use double-sided tape to mount the enclosure under your upside-down tray.
  • You can now attach the nose to your favourite bust, teddy bear or flower pot!
