Ultrasonic Anemometer (Wind Speed and Direction Sensor)

Ultrasonic Anemometer (Wind Speed and Direction Sensor) Product Overview： 

The 2-in-1 Ultrasonic Anemometer is a fully digital, high-precision meteorological monitoring device designed specifically for fast and accurate measurement of wind speed and direction. The sensor uses ultrasonic technology with an integrated signal processing unit and supports RS485 output with standard Modbus protocol. It offers flexible signal output options according to user needs and features no mechanical moving parts, quick response time, long service life, and maintenance-free operation. Additionally, it can optionally measure various environmental factors such as temperature, humidity, atmospheric pressure, PM2.5, PM10, noise, radiation, and rainfall. Its high-strength design and IP65 protection level ensure reliable operation in harsh environmental conditions. The sensor is highly integrated, durable, and widely used in meteorology, environment, airports, ports, laboratories, industries, and transportation sectors.

Working Principle of the 2-in-1 Ultrasonic Anemometer  

The ultrasonic wind speed and direction sensor calculates wind speed and direction by measuring the time difference of ultrasonic wave transmission through air. The sensor utilizes ultrasonic probes in four directions (North, South, East, West) and measures the transmission time of ultrasonic waves from North to South, South to North, West to East, and East to West. For example, when the wind blows from the North, the transmission time from North to South will be shorter than from South to North, while the transmission times from West to East and East to West will be the same. By calculating these time differences, the sensor can accurately determine wind speed and direction, with results unaffected by environmental factors such as temperature. This design with no moving parts increases reliability and durability, making it particularly suitable for long-term outdoor use.
