Building Instructions and Usage


This Project is currently in development, for who is going to build/test this device in this phase, license is provided for FREE.


You can build and use this device without a license for testing purpose. Without a license you can see only the first channel data. Sampling rate is limited.


  • License is bounded in the ESP32 Hardware.
  • Each device (ESP32+sensor) requires a license to work with the full features.
  • Keep the provided license code for a second use in case of firmware update on the same ESP board.
