Most irrigation systems rely exclusively on soil moisture sensors. However, soil moisture sensors can't tell you how much of the present water is actually available to plants. This system uses an MPS-2 matric potential sensor to measure plant available water so you know when to turn the water ON.
Fast-response soil moisture sensors let you track plant water use in real time and set an accurate full point that minimizes wasted water. That way, you'll know when you've reached field capacity and should turn the water OFF.
A pressure switch tracks irrigation events by recording when water is turned on and off. You'll know for sure if irrigation is happening as scheduled.
DataTrac 3 lets you watch the interaction of all the sensors graphically so you get a "roots'-eye view" of your irrigation picture.
MPS-2 Matric Potential Sensor. Goes beyond simple water content data to describe water availability.
5TE Soil Moisture Sensors (2). Locate these sensors within and below the root zone to track water content through the profile.
High Resolution Rain Gauge. Measures both precipitation and irrigation events.
Pressure On/Off Switch. Tracks irrigation events by recording when the water goes on and off.
Em50 Data Logger. Plug in the sensors, set time and measurement intervals, and start logging data. No programming necessary. Monitor wirelessly by upgrading to the Em50R or Em50G.
DataTrac 3 Software. Dynamic graphical interface brings data to life.
For use with deep installation of the ECH2O probes. Includes a regular and sand auger (2.75" [7 cm] diameter), two 2' (0.6 m) extension rods, a standard rubber handle, and a ratchet handle.
