High Capacity, Low Cost Wind Data Logger for wind turbines / wind farms.
The WindLog™ is a compact, inexpensive wind data logger, designed to meet the needs of people considering the purchase of a wind turbine. While many people rely on wind maps to assist them with this purchase decision, these maps don’t provide the detailed information for a specific area. The WindLog allows you to do your own accurate wind study to optimize your turbine placement and its performance, once installed.
Data can be downloaded from the WindLog™ using a 5m USB cable and the no-cost Windows-based WindLogger™ software (WindSoft), which uses a SQLite database to track and record wind information. The logging interval can be set from once a minute to once an hour. USB extenders can be used to lengthen the USB cable to over 10m. The USB cable can be left connected to the WindLog™ allowing real-time viewing of the wind data on a computer. By combining both logged and real-time data WindLog can be used both online and offline. WindSoft can generate statistics, graphs and reports. It can also export CSV files for use with Microsoft Excel or any other application that supports CSV files. Battery life for the logger will depend upon the environment and logging rates. Typical battery life is 6-9 months. When connected to a computer the WindLog™ will use the USB port power to run. This further extends the life of the batteries. The Mini-Aervane wind sensor is equipped with low friction race bearings. This reduces the threshold to approximately 0.45 M/S. The wind direction sensor has a 16-point resolution. Logged direction readings are averaged readings. A support mast is included with the WindLog™. This mast can be used with the Rainwise® Mono Mount or tripod. The mast may also be attached to a support structure using U-Bolts or lag screws.
