-This is the code for the AirGradient Open Air open-source hardware outdoor Air
-Quality Monitor with an ESP32-C3 Microcontroller.
-
-It is an air quality monitor for PM2.5, CO2, TVOCs, NOx, Temperature and
-Humidity and can send data over Wifi.
-
-Open source air quality monitors and kits are available:
-Indoor Monitor: https://www.airgradient.com/indoor/
-Outdoor Monitor: https://www.airgradient.com/outdoor/
-
-Build Instructions:
-https://www.airgradient.com/documentation/open-air-pst-kit-1-3/
-
-The codes needs the following libraries installed:
-“WifiManager by tzapu, tablatronix” tested with version 2.0.16-rc.2
-"Arduino_JSON" by Arduino Version 0.2.0
-
-Please make sure you have esp32 board manager installed. Tested with
-version 2.0.11.
-
-Important flashing settings:
-- Set board to "ESP32C3 Dev Module"
-- Enable "USB CDC On Boot"
-- Flash frequency "80Mhz"
-- Flash mode "QIO"
-- Flash size "4MB"
-- Partition scheme "Default 4MB with spiffs (1.2MB APP/1,5MB SPIFFS)"
-- JTAG adapter "Disabled"
