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"

/*
|
||||
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"
