The idea

Show current airborne particulate matter concentration using a LED light in a lamp, inspired by http://stoflamp.nl The data that the LED colour is based on is simply retrieved over WiFi from the luftdaten website.

This lamp is a plastic pine apple ("ananas"), bought at the "Action" store.

Concepts/ideas:

  • The lamp shows particulate matter concentration as a colour, e.g. soft/positive colours for low concentration and hard/bright colour for high concentration
  • The lamp "breathes" by varying the intensity over time, e.g. a cycle of 10 seconds where the light dims a bit and brightens a bit. Perhaps we can increase the breathing rate as well for higher PM.
  • The lamp retrieves the PM value over wifi from the the luftdaten website

Nice to have:

  • Automatic determination of location by means of wifi location
  • Remote control over IR

Hardware

right The lamp is controlled by an ESP8266, a Wemos D1 mini board. The LEDs used has a built-in PL9823 controller.

Software

Software is available on github.

Libraries:

  • WiFiManager is used to manage WiFi connection to the local AP
  • FastLED is used to control the LED
  • ArduinoJSON for the parsing the luftdaten response
