a simple device uses ESP32 to interract with a serial device (can be another MCU, a sensor or basically anything using serial communication) via webUI.
datalogging capabilities using built in flash (+sdcard support later).
if using 3v3 boards (like the ESP32) to monitor a 5v sensor, a level shifter should be added
(though a simple voltage divider, while not the best solution, is sometimes sufficient)
proper WebUI will be imlemented soon. right now to view the newlines correctly, you can 'view source' on the address, so you can see the serial data as-is.
receive-only right now. sending data to the sensor will be implemented later.
hardcoded to 115200, change manually in the code to the desired data rate.
