Self heating exploration
4 hours ago • 0 comments

Milling an island around the BME688 environmental sensor helps prevent heat from flowing from the Wi-Fi module and voltage regulator to the right of it. However, it is not possible to totally avoid the PCB self-heating. Therefore, I added an offset slider for temperature and relative humidity measurements to the UI. This can also compensate for offsets due to mounting issues and the housing.
