The Veswe Ultrasonic Wind Sensor is a professional anemometer developed based on advanced ultrasonic wave principles. It calculates wind speed and direction by measuring the time or frequency difference (Doppler transform) of transmitted sound wave pulses at the receiving end.
Featuring a non-mechanical design, this sensor can simultaneously capture the instantaneous values of both wind speed and direction. It provides real-time, high-resolution data for meteorological monitoring, environmental assessment, and industrial wind measurement applications.

About - Ultrasonic Wind Speed Direction Sensor
The ultrasonic wind sensor is a more advanced instrument for measuring wind speed and direction. Because it overcomes the inherent shortcomings of mechanical anemometers, ultrasonic win sensor can work normally all-weather and for a long time, and is more and more widely used. It will be a powerful substitute for mechanical anemometers. We provide a free cloud platform for you to view data, with a one-year warranty and support customization.
คุณสมบัติ
The ultrasonic wind speed direction sensor has the characteristics of lightweight, no moving parts, sturdiness, and durability, and does not require maintenance and on-site calibration. It can output wind speed and direction at the same time. Customers can choose wind speed units, output frequency, and output format according to their needs. This ultrasonic wind sensor can be used in conjunction with a computer, data collector, or other collection equipment with RS485 or analog output. If necessary, multiple units can be used to form a network.
Our ultrasonic wind speed and direction sensor features a built-in electronic compass, eliminating the need for directional adjustment during installation—simply ensure it is mounted level. The housing is made of high quality waterproof ABS material, offering lightweight construction and excellent stability, with minimal maintenance and calibration required. This sensor is widely applicable for meteorological monitoring, maritime and aviation operations, port logistics, laboratories, agriculture, and road traffic management.

How Does an Ultrasonic Wind Sensor Work?
หลักการการทำงาน
- The working principle of the ultrasonic wind sensor is to use the ultrasonic time difference method to measure wind speed and direction. Because the speed of sound in the air will be superimposed with the speed of airflow in the wind. If the propagation direction of the ultrasonic wave is the same as the wind direction, then its speed will increase. Conversely, if the propagation direction of the ultrasonic wave is opposite to the wind direction, then its speed will slow down. Therefore, under fixed detection conditions, the speed of ultrasonic propagation in the air can correspond to the wind speed function. The precise wind speed and direction can be obtained by calculation. As the sound wave propagates in the air, its speed is greatly affected by temperature; the wind speed sensor detects two opposite directions on the two channels, so the effect of temperature on the sound wave speed can be ignored.

FAQs - Ultrasonic Wind Speed Direction Sensor
When operating in harsh environments, it is important to keep the sensor’s transducer surface clean. Ultrasonic wind sensors generally have no mechanical moving parts, but accumulated dust, water, bird droppings, or ice on the transducer can affect sound wave propagation and measurement accuracy.
Clean the sensor with a soft cloth or lint-free cotton. Use clean water or a small amount of neutral detergent if necessary, and avoid strong acids, strong alkalis, or corrosive solvents. Since the transducer is a precision ultrasonic device, do not scrape or strike it with hard objects.
Regularly inspect the sensor housing, mounting brackets, and screws for looseness or corrosion to ensure stability. Also check signal and power cables for aging, damage, or looseness to prevent short circuits or signal loss. For models equipped with rain shields or protective covers, periodically remove accumulated water or snow to maintain optimal performance.
When selecting an installation location, avoid strong interference sources, such as high-power motors, variable frequency drives, or large metal obstacles, which can affect ultrasonic wave propagation. Wind speed and direction measurements require an open area, ideally at least 10 meters above the ground. Avoid buildings, trees, or other obstructions that could create turbulence and impact data accuracy.
If your device does not include an electronic compass, ensure that the “N” mark on the sensor points to true north when installed level. If your device includes an electronic compass, simply install it horizontally—no directional adjustment is necessary.
The sensor supports a wide voltage DC power input of 12–30V. When connecting the RS485 signal lines, ensure that the A and B lines are not reversed, and that device addresses do not conflict when multiple units are connected on the same bus.
Wiring Instructions:
- Brown wire: Connect to power positive (12–30V DC)
- Black wire: Connect to power ground (GND)
- Yellow (or green) wire: Connect to RS485-A
- Blue wire: Connect to RS485-B
The sensor uses a default 12–30V DC power input. For devices with 0–10V output, supply 24V DC.
Wire Color Assignments:
- Brown wire: Power positive (V+)
- สายสีดำ: สายกราวด์ (GND)
- Yellow wire: Wind speed signal positive
- White wire: Wind speed signal negative
- Blue wire: Wind direction signal positive
- Green wire: Wind direction signal negative
Possible causes:
1. Obstructions around the sensor (such as buildings or trees) causing local turbulence.
2. The sensor is installed unevenly or at an angle.
3. The ultrasonic transducer is dirty or damaged.Solutions:
1. Install the sensor in an open area.
2. Use a level to check the installation angle.
3. Clean or replace the transducer.
Possible causes:
1. The wind speed is too low, below the sensor’s minimum measurement threshold (typically around 0.01–0.1 m/s).
2. The transducer surface is covered with dust, water, or ice/snow.
3. Data or power lines are faulty, preventing the sensor from outputting a signal.
Solutions:
1. Clean the transducer surface.
2. Check the power supply and wiring.
3. Compare with a reference instrument to confirm whether the low reading reflects actual low wind speed.
- Power issues or insufficient supply: Measure the input voltage to ensure it is stable.
- RS485 or analog signal wiring errors: Check cables, connectors, and communication settings (baud rate, address, etc.).
- Sensor damage or communication failure: If the device is damaged, contact professional technical support. Do not attempt to disassemble it yourself.
