Irrigation zone time control
First Claim
1. A method of controlling irrigation comprising:
- monitoring “
on” and
“
off”
watering signals with a secondary control system that is externally connected to an irrigation controller;
said watering signals being transmitted to each zone of an existing multi-zone irrigation controller over one or more valve control wires;
receiving with said secondary control system a wireless signal representative of at least one irrigation parameter currently existing at a site to be watered;
interrupting an “
on”
watering signal for a particular zone on said one or more valve control wires with said secondary control system based upon an evaluation of said at least one irrigation parameter from said wireless signal.

Abstract
A wireless sensor probe for use in environmental monitoring and control includes a separable probe body and sensor mast. The probe body includes a void configured to house the sensor mast including one or more sensor devices for sensing a soil property surrounding the probe body when the probe body is inserted partially into the ground. The probe body includes a probe top part for encapsulating the probe body and the sensor mast. The sensor mast is inserted into the probe body to form the sensor probe. In another embodiment, a wireless sensor probe includes a housing containing one or more sensor devices. The probe further includes a collar situated near a top portion of the housing being used to anchor the housing to the top of the ground and a gasket formed on the outside perimeter of the housing for securing the housing in the ground.

8. A control system for adjusting an irrigation schedule of an irrigation controller comprising:
-
a sensing device configured to monitor a watering command signal of said irrigation controller communicated on one or more valve control wires; a receiving device configured to receive at least one wireless signal representative of at least one irrigation parameter currently existing at a site to be watered; an interruption device configured to interrupt said watering command signal communicated on said one or more valve control wires based on an evaluation of said at least one irrigation parameter from said wireless signal; wherein said control system is externally connectable to said one or more valve control wires of said irrigation controller. - View Dependent Claims (9, 10, 11, 12, 13, 14)
