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
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
