Do you know what is this?
This is the prototype wind sensor. Usually, wind speed or direction sensors have some propeller or wing, etc. But these physical movements are weak at very strong windy location such as here at Denali (Mt. McKinley). Always broken!
Our main goal is to measure ground (permafrost) temperature but we add wind measurements. very unique one! This prototype sensor has 4 strain gages when the pole vent little bit to detect wind speed and direction. Accuracy is less than normal wind sensors but stronger (because no physically moved)!
