Watermark Irrometer Soil Moisture Sensor Module Monitoring WEM-DC-T

This is a new old stock Watermark Irrometer Soil Moisture Sensor Module Monitoring WEM-DC-T

The WATERMARK Electronic Module works in conjunction with a residential or commercial type irrigation controller to suspend irrigation when soil moisture status is appropriate for good plant heath. The included WATERMARK soil moisture sensors are placed in the root zone of the plant material being irrigated and wired to the WEM. The WEM can be used to manage a single valve, a group of valves (hydrozone), or the entire irrigation controller. When the controller attempts to activate irrigation, the WEM intercepts the signal and then interrogates the sensor for soil moisture status. If the soil is wetter than the set point, the system will prevent the irrigation cycle.
