1.0 Introduction
The Weather Center II is comprised of four major measurement sensors,
these include:
•
The Solar Radiation Sensor
•
Temperature/Relative Humidity Sensor
•
The Rain Fall Sensor
•
The Wind Speed Sensor (Anemometer)
The Weather Center II calculates Evapotranspiration (ET) and measures
rain and wind speed. The measured sensor values are received by the
Rain Master Weather Computer which resides inside the attached
Evolution DX2/Eagle Controller. The Weather Computer, using the
various sensor inputs, will then calculate and output, as necessary, a
controlled pulse for each 0.01 inches of ET. The pulse which is output
by the Weather Computer is received, stored and provided to the
Evolution Central Computer system as requested (or used by the RME
Eagle Controller directly and provided to the iCentral as requested). The
Evolution Central Computer system uses the weather data to recalculate
the irrigation schedules for all satellites associated with a particular
microclimate. The new schedule is then downloaded to the field
irrigation controllers.
Each of the measuring devices is permanently mounted onto a vandal-
resistant tower with all connections made within the tower’s terminal
block. Power for the Weather Computer is supplied via the Evolution
DX2 controller enclosure to which the Weather Center II is connected.
