WS PRO Weather Stations
Optimize Irrigation With Automatic Weather-Sensitive Scheduling!
Eliminate unnecessary watering and
reduce costs with Rain Bird’s WS PRO
and WS PRO LT Weather Stations. When
used in conjunction with Rain Bird
Central Control Systems (Cirrus™,
Nimbus™ II and Stratus™ II), weather
stations will provide the weather data
needed to optimize irrigation watering
times, reduce water usage and limit or
eliminate turf damage.
The WS PRO and WS PRO LT Weather
Stations are highly accurate, durable and
reliable. They are built using the finest
components, material and sensors
available and will provide years of
reliable data even in the toughest
environments. As an example of the high
level of craftsmanship used, sensors are
attached to the body of the weather
station using sealed connectors.
The WS PRO and WS PRO LT stations
measure air temperature, relative
humidity, wind speed and direction, rain
fall and solar radiation. In addition, the
WS PRO LT also measures barometric
pressure. Both models are available with
an optional solar panel and direct
connect connection for up to a 20,000 ft
range. The WS PRO LT also has a wireless
communication option and the WS PRO
a telephone one.
Rain Bird’s Weather Stations are
easy to install and come with a
weather ready protective case with
on board microprocessors and
rechargeable batteries.
Connected with Rain Bird’s Central
Control, the WS PRO and WS PRO LT
Weather Stations will unleash the
innovative and industry leading features
of the Smart Weather module.
Features and Benefits
Superior ET Model – Rain Bird’s Central
Control Systems use weather sensor
input to determine evapotranspiration
(ET) rates based upon a field-proven
proprietary equation for ET.
Automatic ET Download/Selective
Usage – Automatically download
weather data daily and calculate ET to
determine irrigation times for the
entire system or specific areas, holes
or stations.
Rain Bird’s WS PRO LT provides the environmental
data you need for The Intelligent Use of Water.
™
ET Override – Allows you to easily set
certain programs to ignore ET values
when determining run times.
Rain Bucket – Allows rainfall from one
day to be carried over to the following
day(s) for more accurate ET calculations.
Multiple Station Capacity – Connect up
to five weather stations to one central
control system for more precise ET
values based upon different weather
conditions around the golf course.
Max Rain Fall – User-defined Max
Rain Fall can be set to limit the amount
of acceptable rainfall for clay soil
types or other areas that are subject to
high runoff.
Weather Data Reports – Generate
reports to show current or past weather
conditions by the hour, day, week,
month or year.
Unlimited Data Storage – Store
unlimited weather data at the
central control.
Multiple Languages – Choose from
ten different languages (English, French,
German, Italian, Japanese, Korean,
Portuguese, Spanish, Swedish
or Chinese).
English or Metric Measurement Units –
Select between English or Metric units
of measure.
The WS PRO Weather Station goes a step
further by working with the central
control system, generating alarms for:
• Rain
• High or Low Ambient Temperatures
• High Winds
• Rainfall Intensity
…that exceed user-defined thresholds in
user-defined time periods. The system
will reset alarms automatically when
temperature, rain or wind conditions
are again within acceptable ranges
for irrigation.
• Automatic Shut Off/Turn On –
Rain Bird Central Control Systems
automatically shut OFF irrigation to
the entire system or to specific areas
only (teebox, fairway, green, etc…)
when alarm conditions are detected at
the weather station. They also
automatically turn ON irrigation when
weather conditions return to the
acceptable range for irrigation.
• Automatic Pause/Resume – Rain Bird
Central Control Systems automatically
suspend irrigation to the entire system
or specific areas only (teebox, fairway,
greens, etc…) when alarm conditions
are detected by the weather station.
They also automatically resume
irrigation when weather conditions
return to the acceptable range
for irrigation.
• Automatic Notification – The WS PRO
Weather Station can automatically
notify you wherever you are, at the
central control or via paging, text
messaging or e-mail when alarm
conditions exist.
The WS PRO sensor
array records vital
weather information
and sends it to
your computer.
