The WD-1 Water Detector can be used to monitor soil or a space for water, as a leak detector. The other way to use the WC-1 is as a water check monitor. When used in this manner, the Water Detector is placed where runoff will collect (or where water is being introduced into the growing medium). Each output (solenoid or pump) on the Aqua-x can be “assigned” to a specific WD-1. Each time the solenoid or pump assigned to the WD-1 is activated by the Aqua-X, the WD-1 must detect water within an adjustable time delay. If water is not detected (pump or solenoid failure), the Aqua-X will send an alert to the user notifying them of “irrigation failure.” Up to 25 WD-1’s can be connected to a single Aqua-X.

Use two water sensors (WD-1/2) to activate the new auto-fill feature on the Aqua-X Pro. One water sensor will be placed at the bottom of the nutrient reservoir and one at the top of the reservoir. When the liquid level drops below the bottom sensor, the Aqua-X Pro will activate a solenoid, or pump, and the tank will fill back up to the sensor at the top.
