Ultrasonic wind speed sensor is a fully digital detector, high-precision sensor, integrated by the ultrasonic wind speed and direction sensor. It can accurately and quickly detect wind speed and direction; the built-in signal processing unit can output corresponding signals according to user needs. The structure is light and compact, with no moving parts, and the high-strength structure design can accurately detect under harsh weather conditions and produce accurate and stable components. Low maintenance cost, open communication protocol and other characteristics, can be widely used in meteorology, ocean, environment, airport, port, laboratory, industry and agriculture, transportation and other fields.
