Spruce Soil Moisture Sensor
Spruce sensors send real-time information about the water levels in your lawn and allows the Spruce controller to adjust the water to the right amount.
Place the sensor in a location where it will be exposed to the spray from the zone of your in-ground irrigation system; ideally, in the middle of the spray zone or a spot that is representative of the zone. The sensor will then relay specific moisture levels in different areas in your garden to the controller and adjust the watering schedule for each zone depending on when and how long the area needs it. The Spruce controller is able to manage up to 16 valves and associated sensors.
The Spruce Sensor is powered by a replaceable battery, which typically last at least one year. Battery status is available in the SmartThings App.
