The WMS-14 Modular Weather
Station is a personal computerbased weather station capable of
simultaneously recording wind
speed, wind direction, temperature,
relative humidity, barometric
pressure, and rainfall. It
automatically measures and stores
outdoor weather conditions at userselected intervals of 1 to 60 minutes
for up to one month in an internal
memory module.
The Model WMS-14 provides a
sophisticated yet way-to-use system
for retrieving, storing, and displaying
information. Data flows to and from
the weather station at speeds up to
9600 BPS using a standard ASCII
terminal protocol via an RS-232
serial interface. With simple numeric
commands, the user can choose to
either view the real time report page
or view the log of historical data.
Data logs are quickly transferred to
a disk file for storage or for graphing
and numerical analysis. A colorful
VGA graphical display is readily
available to view real-time data.
The Model WMS-14 features a
combination wind vane and threecup anemometer with 40 feet of
interconnecting cable (which may
be extended to 300 feet), a
temperature and relative humidity
sensor with sun shield, a solid state
barometric pressure sensor, and, a
self-emptying rain gauge.
