• This document is open source software intended for the development of low-cost data acquisition and telemetry systems for geotechnical instrumentation applications. This software determines all addresses for active SDI-12 (serial digital interface 1,200 Baud) sensors connected to an Arduino microcontroller, and logs data from each sensor. SDI-12 sensors are commonly used for measuring matric suction, volumetric water content and temperature sensor.

  TERMS OF USE:
  The following sketch is to be considered open-source and is largely based on open-source example code from
  https://github.com/EnviroDIY/Arduino-SDI-12.
  Modifications have been made to combine a number of examples and tailor the code to geotechnical use.
  Use of the following open-source code is encouraged to help in the construction of an open-source datalogger.
  For any publications that arise from the use of this code, please cite this permanent link and associated journal paper at:
