Big success for this week was being able to read and interpret the 24bit output signal from the digital tire tread depth gauge.
Then added a SD card and RTC module for data logging capabilities. Everything is looking good after I ran some initial functional tests for each module.
I have decided to move away from the ESP32 initially because wireless data transfer isn't needed for the mechanical proof-of-concept. I have lots of experience with the Arduino Pro Mini data loggers so I can throw one of those together in a couple of hours. The most important thing at this stage of the project to get this device mounted on a tree and see if it can accurately measure tree diameter changes.
