Initial sensor file
Rename file
Read the raw data
Add abilility to parse sensor data

The parsing is currently a bit hacky. The first bit has
to be omitted because I'm not sure where the data
transmission starts. The checksum check also doesn't seem
to guarantee correct values.

TODO:
- Add checksum and range checking
- Modularize into a function

Typo in checksum check
Connect sensor readings to MySQL server

Clean up the read_init.py sensor code.
Tie it to the main python script.
Make modifications to the DB entry code (we now save the unix timestamp,
which is more portable and less prone to parsing error on the app side)

Make the main python script call the sensor function a few times, in
case the first invocations return errors.
