The WMS-25 Modular Weather Stations are
meteorological systems designed to be a “user
friendly” solution for data storage and real-time
monitoring of weather conditions.
The standard sensor package (WMS-25 and WMS-25-NEMA) includes 6 weather
parameters: wind speed and direction, temperature
and relative humidity, barometric pressure, and
precipitation (additional optional sensors can be
added), a 1.5 m (5') tripod and vertical mast for sensor
mounting, and a data logger with LCD display.
No computer is required for setup and viewing data.
A simple menu interface using the LCD display and
three front panel buttons makes setup easy. Data is
recorded directly to a Secure Digital (SD™) card,
providing convenient data downloads and storage for
many months of data. The data logger is compatible
with standard SD cards up to 2GB. Logging at
1 minute intervals, a 2GB card will store over 5 years
of data. A new file is created and saved to the card
Using the recorded data is simple. The SD card is
inserted into a card reader attached to the USB port
on your computer (Windows, Macintosh, and Linux)
and will then show up as a drive. To view and graph
the data, click on the file corresponding to the day
of interest. Microsoft Excel, OpenOffice.org, or any
spreadsheet program can be used to view, graph,
and analyze your data.
