This is the code for the AirGradient DIY Mini Display with an ESP8266 Microcontroller.
|
||||
It can be configures to show the outside air quality as well as one indoor location from the AirGradient platform.
|
||||
|
||||
For build instructions please visit
|
||||
|
||||
https://www.airgradient.com/resources/airgradient-diy-display/
|
||||
|
||||
|
||||
The codes needs the following libraries installed:
|
||||
"WifiManager by tzapu, tablatronix" tested with Version 2.0.5-alpha
|
||||
"Adafruit_ILI9341" tested with Version 1.5.10
|
||||
"Adafruit GFX library" tested with Version 1.10.12 (often automatically installed with above ILI9341 library)
|
||||
"ArduinoJSON" by Benoit Blanchon tested with Version 6.18.5
|
||||
|
||||
Configuration:
|
||||
Please set in the code below (line 90-) if you want to display the PM2.5 values in US AQI and temperature in F.
|
||||
|
||||
If you have any questions please visit our forum at https://forum.airgradient.com/
|
||||
|
||||
|
||||
If you are a school or university contact us for a free trial on the AirGradient platform.
