Description
The Wind Direction Smart Sensor is a research-grade plug-and-play sensor for measuring and logging wind data. It provides average wind direction for the measurement interval. This highly-durable wind vane has a drip overhang for anti-icing. Its shielded stainless-steel ball bearings and static-dissipating housing provide a long sensor long life. The sensor calculates a unit vector average of the wind direction, providing data directly in degrees.
NOTE: a M-CAA Full Cross Arm or M-CAB Half Cross Arm is required for mounting. Please refer to the Recommendations tab.
