Weather Reach Receiver Application Notes
Weather Report - Sentinel 2x Plug-in
“Weather Report” is a software plug-in for EICON’s Sentinel 2x that acquires weather data from a variety of
weather sources. The Weather Reach Receiver (model WR-7) provides weather data, ET and rainfall values for
Weather Report.
The Weather Reach System Water Management System obtains weather data from local weather stations. A
Weather Reach Signal Provider (WRSP) broadcasts a wireless weather signal to Weather Reach Receivers.
Weather information is updated with each broadcast from the WRSP. The local WRSP sets the update
frequency, which can be as often as hourly to once per day.
The WR-7 uses weather date to calculate ET. The Sentinel’s Weather Report software accesses the WR-7 via an
RS-232 serial connection at the computer. When connected to the Sentinel control system the information can
be used throughout the system.
Hardware / Software Requirements
One WR-7 provides weather data from one weather station. The WR-7 is configured as one “Weather Station”

Weather Reach Setup
ET / Rain Setup
Local Crop Coefficient (Kc) = Set this value to calculate ETc (ETo x Kc = ETc)
Local Wind Coefficient = Set to adjust wind value for prevailing wind conditions.
Default Daily ET = If no weather no weather data is received for 25 hours then this ET value is
used. Version 1 units, default to be set by the user. Version 2 units Default Daily ET is set
initially by the user but after 7 days is updated automatically based on ET recorded for the last 7

by the WRSP.
Receiver Units = English or Metric – user option.
Rain = Local (an on-site rain gauge connected to the WR-7) or Broadcast (WRSP signal).
Broadcast Coefficient = Ignore or Use – The WRSP includes a local Kc value to calculate ETc
(ETo x Kc = ETc). Set to ignore for ETc = ETo.
