The Wind Data Logger is designed to provide an affordable and easy to use solution to wind site evaluation and monitoring wind generator performance. It records wind speed, wind gust, wind direction, time and date, temperature, battery voltage, and other important wind parameters. The Wind Data logger easily supports both simple and complex monitoring applications. The data logger can be used to record wind speed from a single anemometer, or it can be used for complex studies involving multiple wind instruments and other sensors. The Wind Data Logger records directly to a Secure Digital (SD™) card. No special computer interface cables are required and the software can easily be viewed and analyzed using standard spreadsheet software.
