Irrometer WS-AC Waterswitch-AC, 1 Watermark Sensor

The WaterSwitch works with existing valves or controller to improve irrigation efficiency based on plant demand. The module will prevent irrigation cycles by signaling the controller's sensor circuit or interrupting the solenoid power, when the soil moisture status is wetter than the adjustable set point. The kit includes one moisture sensor. Nine moisture set points allow for a wide range of variations in plant and soil type. An indicator light flashes to indicate status.

Features:

• WS-AC works with AC powered controllers with a sensor circuit or as a common interrupt of the valve wiring
• Suspends irrigation cycles based on soil moisture status
• Nine position switch for variations in plant demand and soil type
• Requires no seasonal adjustments
