Rain Bird Rain Check Rain Sensor
Monitors rainfall levels and overrides controller to prevent
Adjustable stainless steel sensing
probes offer the flexibility of triggering the rain shutoff
with as little as 1/8" (3,2 mm) of precipitation or when
rainfall reaches or exceeds 1/2" (12,6 mm).
Hydro-mechanical design allows automatic return-to-normal watering
schedule when water in rain collector pan evaporates.
Works with all 24 VAC controllers for maximum versatility.
UV resistant plastic construction increases operating life in
Solid-state design provides greater reliability by eliminating
micro switches and thermal devices which may rust and/or wear
Rating of up to three Rain Bird solenoid valves per station
allows for diverse applications.
Rain Bird WRS Series Wireless Rain
Rain Bird WRS Wireless Rain Sensor conserves water by disabling
a 24 VAC sprinkler system when rain is detected. The WRS Wireless
Rain Sensor consists of two (2) main components: a rain collector
unit (the “Transmitter”) which senses rainfall
and a receiver unit (the “Receiver”) which is wired
into the irrigation controller. The Transmitter sends its signal
wirelessly to the Receiver, eliminating the need for wiring.
The user may adjust the sensitivity of the rain collector to
rainfall levels between 1/8 inch and 3/4 inch.
Wireless connection between the Transmitter and Receiver enables
fast, easy, and attractive installations.
Three LEDs on the Receiver display the sensor state (Watering Suspended; Low
Battery; No Signal) or mode (Sensor Bypass; Test Mode; Program Mode).
Additional Transmitters and Receivers can be programmed to work together by
the installer. This allows multiple Transmitters to work with a single Receiver
or one Transmitter to work with multiple Receivers.
Low Transmitter battery indicator on the Receiver.
Loss of signal indicator informs user when two consecutive hourly transmissions
have been missed.
Integrated bypass switch and status indication on the receiver.
Program Mode enables up to five (5) transmitters to work with one Wireless
Test Mode allows a single installer to validate installation with a two and
a half (2 1/2) minute test signal at low power.
Compatible with virtually all 24 VAC controllers.
Interchangeable and programmable receiver/transmitter pairs.

20 VAC – 28 VAC
Wireless Rain Sensor must be capable of 500 foot line-of-sight
communication between the Transmitter and Receiver *. Transmitter
must be battery powered and capable of lasting three (3) years
without replacement. Transmitter must allow battery to be replaced
without breaking the waterproof integrity of the electronics.
Rain sensor must be water-tight and capable of outdoor installation.
Receiver must be able to receive signals from multiple Transmitters.
Receiver must have Sensor Bypass mechanism. Wireless Rain Sensor
must be able to sense rain and interrupt the 24 VAC irrigation
schedules based on a user-selectable sensitivity to rain quantity.
Wireless Rain Sensor must periodically test the signal from
the Transmitter. The Transmitters must be interchangeable.
Any Transmitter must work with any Receiver from Rain Bird
Corporation. The Rain Bird WRS Wireless Rain Sensor shall be
manufactured by Rain Bird Corporation, Glendora, California.
* Wireless devices using radio frequency communications are
affected by location specific conditions. The reported distance
is based on ideal line-of-sight testing. Actual range may vary
due to atmospheric conditions, terrain, or other forms of interference.
Concept of Operation:
The transmitter is mounted in an area most likely to receive
representative rainfall without running a wire back to the
controller. Wireless Rain Sensor sensitivity is adjusted to
user-desired system responsiveness to rainfall. An RF signal
is sent from the Transmitter to the Receiver every hour or
when the user-selected rainfall has been received. After the
Transmitter dries, a signal is sent that allows the resumption
of irrigation if necessary. Receiver disables watering system
through the Irrigation Controller’s “sensor” connections
or by interrupting the valve common. The receiver can be programmed
to receive up to five (5) wireless sensors. Simple to install
and test by one installer. Test Mode sends a low-power signal
for two and a half (2 1/2) minutes, allowing installer to return
to Receiver and verify proper operation.
