WS PRO2 Weather Station

Maxicom²®, SiteControl, IQ™ v3.0

The WS-PRO2 Weather Station collects and stores weather data from field locations. This information is retrieved by the Central Controller daily, allowing SiteControl, IQ v3.0, and Maxicom² ® to adjust station run time and/or schedule day cycle frequency according to each day’s ET (evapotranspiration) and rainfall.

WS-PRO2 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
  • State-of-the-art weather software calculates ET values, stores daily and historic ET values, monitors and displays current weather conditions, and graphically displays weather parameters
