Methods and apparatus are provided herein for sensing rain fall for use in irrigation control. In one embodiment, a wireless rain sensor comprises a housing at least partially covering a first sensor, a controller and a wireless transmitter. The first sensor comprises a moisture absorptive material located to be contacted by rain fall and configured to expand in response to the contact with the rain fall and contract in response to an absence of the rain fall. The controller is coupled to the first sensor and configured to output signals corresponding to a variable amount of expansion and contraction of the moisture absorptive material. The wireless transmitter is configured to transmit wireless signals, at least one wireless signal comprising data corresponding to the variable amount of expansion and contraction of the moisture absorptive material.

Sensor device for use in controlling irrigation

Some embodiments provide an interface unit interfacing with an irrigation controller, comprising: a housing; a controller configured to instruct an interruption of a watering schedule executed by the irrigation controller, the interruption based on one or both of sensed temperature and sensed rainfall amount, and based on one or both of user entered temperature and rainfall threshold parameters; a switching device coupled with the controller, and configured to cause the interruption in response to signaling from the controller; and a user interface comprising: a plurality of user input devices configured to provide signaling to the controller based upon user's engagement, and configured to allow the user to define the temperature and rainfall threshold parameters; and a user display comprising a display screen; wherein the controller is configured to cause the display screen to display a plurality of pictorial representations that in combination convey whether irrigation is being interrupted.

User interface for a sensor-based interface device for interrupting an irrigation controller

An irrigation emitter is provided for delivering irrigation water from a water supply conduit, such as an irrigation supply tube, pipe, or other water supply apparatus, at a low volume or drip-like flow rate. The emitter operates generally through the use of a reduced size orifice and a relatively long tortuous flow channel that cause a pressure reduction between the water supply conduit and an emitter outlet. The emitter includes an inlet for tapping a portion of the water flow from the water supply conduit and, when the water pressure is above a predetermined minimum level, directing the flow to and through the flow channel for subsequent discharge to a desired location. The emitter also may regulate to accommodate for changes in supply pressure. The emitter also may include multiple emitter outlets.

Low flow irrigation emitter

A root watering system has a porous body and an end assembly connected to the porous body. The end assembly has a fluid emitter and integrally defines an inlet passage for directing fluid to the fluid emitter for providing fluid to the porous body. The assembly also may be fitted with an integral valve.
