Many thanks to them and all my donors🙏🏻
This project is a little air quality monitor for M5Stack and Unit CO2 (SCD40).
First, edit platformio.ini file and change default_envs target :
default_envs = corefor Core,default_envs = core2for Core2default_envs = cores3for Core S3.
You can compile the source code and flash your M5Stack.
Connect Unit CO2 to port A (I2C).
Use middle button to enter the settings menu. Use the right and left buttons to select a menu option and confirm with the middle button. If necessary, use the right and left buttons again to select the sub-options and the middle button to confirm.
The following options are available :
| Settings | Value |
|---|---|
| Temperature Unit | Set Temperature Unit (Celcius or Fahrenheit) |
| Led Alert | Set CO2 PPM Level (0 ~ 5000) |
| Brightness | Set Brightness (0 ~ 100%) |
| Sensor Port | Set Sensor Port (PORT A, PORT C for M5GO2, PORT C for M5GO3) |
| Beep | Set Beep (0 ~ 100%) |
| Shutdown | Shutdown your M5Stack (even if in charge) |
| Reboot | Rebbot your M5Stack (even if in charge) |
| Exit | Menu Exit |
Note
About Led Alert, set CO2 PPM to 0 if you want to use de default animation (green < 1000ppm, yellow < 2000ppm, orange < 3000ppm or red).
Note
Temperature Unit, Led Alert, Brightness, Sensor Port and Beep are preserved at the next restart.
