Vaavud ultrasonic wind meter
The Vaavud Ultrasonic is the world’s first fully autonomous, smart-phone connected, ultrasonic anemometer – solar powered and Bluetooth connected.
It has no wires, is super compact, and weighs only 130 grams, so you can mount it practically anywhere!
Four ultrasonic transducers register wind flow with 0.1 m/s / 1 degree accuracy and sensibility, and since the device has no moving parts it is extremely durable.
A number of onboard sensors along with the GPS in your smartphone/tablet ensure accurate measurements of both apparent and true wind even if the device is moving.
