In order to overcome the shortcomings of traditional mechanical anemometers, ultrasonic anemometers came into being. The ultrasonic anemometer does not require mechanical moving parts, but is replaced by multiple ultrasonic sensors, regardless of the impact of external environmental wear, high precision and more convenient installation.At present, the 8/16 single-chip microcomputer is more common in the market as the core processor of the ultrasonic wind speed measurement system. This design is based on the design and implementation of the ultrasonic wind speed measurement system with C8051 microcontroller as the core processor.
