ABSTRACT:
A landscaping watering system has a probe for monitoring a moisture content of an area. A control unit is coupled to the probe for sending an activation signal to activate a flow of water when a signal from the probe indicates the moisture content of the area is below a predefined level. The control unit sends a deactivation signal to stop a flow of water when a signal from the probe indicates the moisture content of the area is above a predefined level. A water solenoid valve is coupled to a water line, the control unit and to at least one sprinkler. The water solenoid valve will receive the activation and deactivation signals from the control unit to start and stop a flow of water from the water line to the at least one sprinkler.
