WS-PRO Weather Stations

Optimize Irrigation With Automatic Weather-Sensitive Scheduling


The WS-PRO2 and WS-PRO LT Weather Stations collect and store weather data from field locations. This information is retrieved by the Central Controller daily, allowing SiteControl, IQ v2.0, and Maxicom2 ® (WS-PRO2 only) to adjust station run time and/or schedule day cycle frequency according to each day’s ET (evapotranspiration) and rainfall.

WS-PRO Weather Stations are highly accurate, durable, and reliable. They are built using the highest quality sensors available and will provide years of reliable data even in the toughest environments. An on-board data-logger continually polls the sensors which measure air temperature, relative humidity, wind speed and direction, rainfall and solar radiation.

  • Scientific accuracy sensors located three meters above the ground for added vandal-resistance.
  • Powerful, internal micro-logger for climatic data collection, logging and analysis, constant communication with weather sensors, and storage of 30 days of data.
  • Rugged yet lightweight metal construction.
  • Self-diagnostic test mechanisms: internal moisture, battery voltage level, test port for local sensor check, and simple-to-service sensors and internal components.
  • Sensors monitor 6 ET/weather parameters: air temperature (high & low), solar radiation, relative humidity, wind speed, and rainfall – Wind direction is also measured
  • Sensors located 3 meters above ground for added vandal resistance
  • Simple-to-service sensors and internal components
  • Self-diagnostic test mechanisms: internal moisture, battery voltage level, and test port for local sensor check
  • Internal battery charged by 100-240VAC/16 VDC transformer or optional solar panels
  • Three-year trade warranty.
  • WS-PRO2-DC Direct Connect model – 2-pair wire connection with Central Controller via short-haul modem
  • WS-PRO2-PH Phone Connect model – dial-up phone modem for phone communication with Central Controller
