The 10HS soil sensor has a simple analog voltage output that is easy to measure with an Arduino board by doing an analog voltage measurement. The Teros 12 has a digital output in either TTL or SDI-12 format. I’d recommend SDI-12, especially if you’re going to have more than one sensor connected to the same board, since then you can assign a different address to each one. The simplest library to do all of this is our SDI-12 library.
