WS-PRO2 Weather Station
1.0 General Information
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 and
power.
Rain Bird Smart Weather 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 Smart Weather 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:
• Rainfall
• Wind Speed & Direction
• Air Temperature
• Relative Humidity
• Solar 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 Smart Weather software located on the central control
computer and a power supply.
The Rain Bird Model “PRO 2” Weather Station is available in four (4) basic
configurations:
Model WSPRO2SH - A direct wire system intended for use when the weather
station is within 20,000 feet of the Central Control Computer and communication
is via a wire path between the weather station and the computer. A separate
power source is required for this weather station.
