STORING TO SD CARD
Data in .txt format are stored to SD card every full hour. Each data has date and time stamp.
Logging interval is selectable from 10 sec to 1h. Data are stored in the .txt format and are suitable for processing in
programs for working whit spreadsheet (Excel, Open office, etc...).
Mark “NA” in logged data present missed wind data for marked interval.
Mark “nW” in logged wind direction data present undefined wind direction caused of no wind speed.
There is a rare possibility that individual logged packets could be corrupt due to external causes.
It is recommended to eliminate them during processing logged data.
For each using of new type SD card it is recommended to test writing data to SD card.
STORE DATA FROM SD CARD
It is recommended to store data from SD card every month for preventing data loss because of empty battery in
receiver or other external factors.
DESCRIPTION OF DATA STORED ON SD CARD
[WS]: average wind speed in selected units and logging interval
[WSm]: maximum wind speed in selected units and logging interval
[WSt]: average temperature in selected logging interval
[WD]: average wind direction in selected logging interval
[dd/mm/yyyy]: day/month/year of created logged data
[hh:mm:ss]: hours:minutes:seconds of created logged data
EXAMPLE OF DATA STORED ON SD CARD
Example of logged first 15 wind data from WSD sensor in 10s logging interval. Average wind speed [WS] and
maximum wind speed [WSm] wind speed data are in units of m/s, temperature in degrees of celsius and wind
direction [WD] in degrees.
