GasSensor

GasSensor using Wio Terminal and 4-Channel Gas Sensor Module.

Also uses Edge Impulse for gas classification.

Libraries Used

I didn't use the PlatformIO installer, as I found the libraries were out of date. Instead, I manually installed them into the lib folder.

Throw these in the /lib folder

• Seed Arduino LCD
• Seeed Arduino MultiGas
• Seeed_Arduino_FreeRTOS
• Gas Classifier
  • To build, select "Arduino Library" at the top, the "Build" at the bottom. Extract the resulting folder to your /lib folder
• TFT_eWidget
  • Had to some of the files to fix errors. At this point I should start distributing my own fork of this library.

Simple Chassis

Not required, but I made a 3D printable chassis for the Wio Terminal and the Gas Sensor Module.
