General Overview
This manual describes how to use your WatchDog Weather Station
and how to keep it working accurately for many years. Read this
manual thoroughly in order to make effective use of your weather
station.
The WatchDog Weather Station will allow you to record and monitor
real-time local weather information at remote sites. Your weather
station can also be connected to as many as 4 additional sensors via
the external sensor ports. Through the software, simply configure the
weather station to record the appropriate sensors.
Download the accumulated data at your convenience using the
powerful SpecWare software. SpecWare will present the data in
graphical and tabular form. Use the software to calculate growing
degree days and chill hours, leaf wetness, temperature and RH hours,
or view daily, monthly, and yearly reports. Optional disease and
insect models aid the user with Integrated Pest Management decisions.
Evapotranspiration calculations to aid in irrigation scheduling are also
available with the 900ET station.
