Soil Moisture Sensor with SD logging
WojciechM3 @ instructables.com has build an Arduino based soil moisture sensor with character LCD, real time clock and SD card logging.
It can be very helpful with a master degree biotechnology/biology/botanics works, however remember that kind of a project can be only add as a bonus as it is in my Master thesis. Good luck with building it!
