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

Several embodiments provide wireless irrigation system and related methods. In one implementation, an irrigation system includes a plurality of valves; a plurality of solenoids; a plurality of circuits, at least one circuit in a circuit housing attached at least partially to a dedicated solenoid housing of a respective one of the plurality of solenoids; a plurality of wireless transceivers, at least one wireless transceiver in the circuit housing attached at least partially to the dedicated solenoid housing of the respective one of the plurality of solenoids and configured to wirelessly communicate via a communication network; and the communication network comprising the plurality of wireless transceivers for communication with the plurality of solenoids.

Wireless irrigation control

Several embodiments provide wireless irrigation control and related methods. In one implementation, an irrigation control system includes a transmitter unit including a controller and a connector to be coupled to an irrigation controller having station actuation output connectors. The controller is can receive an indication that the irrigation controller has activated an irrigation station, and can cause the transmitter unit to transmit a wireless activation signal responsive to the indication. A receiver unit is coupled to an actuator coupled to an actuatable device, such as an irrigation valve, the actuator configured to actuate the irrigation valve to control the flow of water therethrough. The receiver unit receives the wireless activation signal and in response, causes the actuator to actuate the actuatable device.
