Ultrasonic wind speed, handheld version
Friday gizmo: Davis just announced WindScribe, a $129 ultrasonic wind speed sensor that apparently uses some of the technology seen in Airmar’s WeatherStation. WindScribe also measures temperature and computes wind chill, and can be mounted using an included bracket. There’s nothing up on the Davis Web site yet but it will probably go in this section of wind indicators. One thing I don’t understand in the press release is the gadget’s ability to “monitor maximum headwind, maximum tailwind, 5-second average and running average.” How can you measure head and tail winds without knowing your own speed?
