The combination Wind Speed and Direction Smart Sensor provides average wind speed, highest three second wind gust and average wind direction in the measurement interval. Designed with a large wind vane area for high sensitivity, the Wind Speed/Direction Smart Sensor offers high accuracy at an affordable price. This model measures average wind speed, highest three second wind gust and average wind direction (unit vector average) and utilizes anodized aluminum and stainless steel construction for durability in adverse conditions. Wind speed sensor has fiberglass reinforced thermoplastic cups and shielded stainless steel ball bearings for fast response. Wind vane has metal bushings.

| Measurement Definition | Cup revolutions are accumulated every three seconds for the duration of the logging interval. Wind speed is the average speed for the entire logging interval. Gust speed is the highest three-second wind recorded during the logging interval. | Vector components of wind direction are accumulated every three seconds for duration of logging interval. Average direction is calculated from the sum of the vector components every logging interval. |
