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.

The wind logger operates on three AA batteries. Battery life will depend on the environment and logging rates. Typical life should be around 6 months. Lithium batteries are recommended for cold environments. When connected to a computer the WindLog will use the USB ports 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 1 mile per hour.  The wind direction sensor has a 16-point resolution. Logged direction readings are averaged readings.

The WindLog samples every second. Both average and gust readings are stored at the the selected interval. With the new 2 MB memory the logger can record for over 3 months a 1 minute rate.

WindSoft - Free Windows Software Package
Each WindLog ships with a free Windows based application, WindSoft. The software uses a SQLite database to track and record wind information. While connected, WindSoft will update the database every minute. Downloaded data is integrated into the database. By combining both logged and real-time data the WindLog can be used both online and offline.

WindSoft, can generate statistics, graphs and reports. It also can export CSV files for use with Microsoft Excel or any other application that supports CSV files.

The WindLog ships with a 15 foot USB cable. This is the maximum standard USB cable length. A USB extender is available that will allow you to extend this cable to 100 feet using CAT5e network cable.

A support mast is included with the WindLog. This mast can be used with the Rainwise Mono Mount, and tripod. The mast may also be attached to a support structure using U-Bolts or lag screws.
