This adapter makes it easy to work with SDI-12 sensors, especially if you are using a Raspberry Pi as your logger. The Documentation is great and so is the communication. Every question or concern I have had has been addressed very quickly. Will definitely buy again. The only reason why i gave a 4/5 on the product is because the terminals are a little too small, but overall this is a great product and easy to work with.

Thanks for your comments! FYI the terminals comfortably accept wires up to 18 AWG (tested). If you have a wire lead, you should tin the lead and trim it to the right length as suggested in the manual before inserting it. I'll design another variation with larger terminals but I have never seen any SDI-12 sensors using thicker wires than 18 AWG.
