1. Introduction
The Rain Bird WS-PRO2 Weather Station, when used in conjunction with the Rain Bird Cirrus,
Nimbus II, or Stratus II Central Control system, provides the irrigation professional with a
powerful tool to aid in the growing of lush, healthy, green turf grass, while conserving important
resources, such as water, power, etc.
Rain Bird SmartWeather software interrogates the WS-PRO2 weather station to retrieve
information that has been gathered on a daily basis of the climatic conditions that affect the
irrigation application for the area.
The SmartWeather software subjects the climatic information that it gathers to a version of the
modified Penman Equation. The Penman Equation has been proven through over 35 years of
university research to be one of the most reliable predictors of turf grass water use requirements.
The weather station monitors the following climatic conditions:
lRainfall
lWind speed and direction
lAir temperature
lRelative humidity
lSolar radiation
The standard WS-PRO2 configuration includes sensors to monitor these conditions, a data
logger to capture this data, a modem to communicate the information to the SmartWeather
software located on the central control computer, and a power supply.
Section1. Introduction1

2. Precautions
lREAD AND UNDERSTAND the Safety section at the back of this manual.
lDANGER: If any part of the weather station comes in contact with power lines, you could be
killed. Contact local utilities for the location of buried utility lines before digging or driving
ground rods.
lAvoid dangerous electrical accidents when using the AC power option by locating the
transformer remotely and burying a low voltage line to the station. The low voltage will
carry up to 152m (500ft) on an 18 AWG power cable.
lCarefully handle the WS-PRO2 components during transport, installation, and cleaning.
lLeave the 034B wind vane in the protective cardboard sleeve until it’s ready to be installed.
lEnsure to remove the yellow cap from the RH and temperature sensor, the red or green
cap from the pyranometer, and the rubber band from the tipping bucket mechanism. Save
the caps for shipping or storing the sensors.
lWhen connecting cables to the enclosure panel, ensure that each plug is completely seated
on the connector and the locking ring is turned a quarter revolution clockwise. Failure to
seat the plug completely could cause corrosion and water damage to both the enclosure
and the cable.
lWARNING: Misuse of the lithium battery in the data logger or installing this lithium battery
improperly can cause severe injury. It is a fire, explosion, and severe burn hazard! Do not
recharge, disassemble, heat above 100 °C (212 °F), solder directly to the cell, incinerate, nor
expose contents to water. Lithium batteries need to be disposed of properly. Refer to Data
logger module (p. 69) for more information.

Section4. QuickStart9

5. Siting and exposure
DANGER:
If any part of the weather station comes in contact with power lines, you could be killed.
Contact local utilities for the location of buried utility lines before digging or driving ground
rods.
Selecting an appropriate site for the weather station is critical to obtain accurate meteorological
data. In general, the site should be representative of the general area of interest, and away from
the influence of obstructions such as buildings and trees.
The weather station should not be located where sprinkler irrigation water will strike sensors or
instrument enclosure.
Some general guidelines for site selection are listed below, which were condensed from EPA
(1988), WMO (1983), and AASC (1985) publications. See References (p. 79).
5.1 Wind speed and direction
Wind sensors should be located over open, level terrain, and at a distance of at least ten times
(EPA) the height of any nearby building, tree, or other obstruction (FIGURE 5-1 (p. 10)).
FIGURE 5-1. Effect of structure on wind flow
Section5. Siting and exposure10

5.2 Temperature and relative humidity
Sensors should be located over an open, level area at least 9m (29.5ft) (EPA) in diameter. The
surface should be covered by short grass, or where grass does not grow, the natural earth
surface. Sensors should be located at a distance of at least four times the height of any nearby
obstruction and at least 30m (98.43ft) (EPA) from large paved areas. Sensors should be
protected from thermal radiation and adequately ventilated.
Situations to avoid include:
llarge industrial heat sources
lrooftops
lsteep slopes
lsheltered hollows
lhigh vegetation
lshaded areas
lswamps
lareas where snow drifts occur
llow places holding standing water after rains
5.3 Solar radiation
Pyranometers should be located to avoid shadows on the sensor at any time. Mounting it on the
southernmost (northern hemisphere) portion of the weather station will minimize the chance of
shading from other weather station structures. Reflective surfaces and sources of artificial
radiation should be avoided.

Section6. Installation12

FIGURE 6-1. WS-PRO2 pole base installation
1. Construct the concrete form with 5 cm x 10 cm (2 in x 4 in) lumber and 16p nails.
2. Assemble the template and anchor bolts. For each bolt, place two nuts below and one nut
above the template.
3. Clear an area large enough to set the form at the desired elevation.
4. Dig a hole 0.6 m x 0.6 m x 0.6 m (2 ft x 2 ft x 2 ft). Lighter soils may require a deeper hole.
5. About 50 cm (20 in) below the top of the hole, gouge a small cavity in one wall of the hole.
The cavity should be about 10 cm (4 in) deep and just large enough in diameter to insert
one end of the conduit. Make certain the cavity points in the direction from which power
and communications cables will come. For example, the cavity will point towards a valve
box if one is being used.
6. Center the form over the hole. Adjacent to the form, drive four stakes into the soil. Secure
the leveled form to the stakes with the 8p nails.
7. Cap the ends of the conduit with duct tape.
8. Position the conduit then wire into place by securing the wire to nails in the form.
9. Fill the hole and form with approximately 0.5 m (0.5 yards) of concrete. Screed the concrete
level with the top of the form.
10. Center the template assembly over the conduit and press into the concrete.
Section6. Installation13

11. Put 2-by-4 spacers between the template and the top of the form. The bottom of the bolt
threads should be about 1 cm (0.5 in) above the concrete (FIGURE 6-2 (p. 14)). The template
must be level in two dimensions.
