WM200 Watermark soil water tension sensor interface

The WM200 provides 5 connections for Irrometer Watermark 200 sensors and provides an SDI-12 interface for the Agility® Sensor Radio. In expansion SDI-12 connection is also provided to allow for connection of additional SDI-12 sensors. One example frequently used by researchers is to connect a Sentek volumetric sensor for direct comparison of volumetric water content and tension.
