What instruments measure wind speed and direction?

Wind speed and wind direction are two very important elements in the field of meteorological monitoring. If you want to monitor data changes in real time, you need to use specific instruments. What is the name of the instrument used by the weather station to measure the wind speed and direction? The wind speed sensor is used to measure the wind speed, and the wind direction sensor is used to measure the wind direction. In addition, ultrasonic integrated sensors are also very popular now.

What is the name of the instrument used in the weather station to measure wind speed and direction?

Usually, mechanical sensors or ultrasonic sensors can be installed to monitor both environmental elements. The mechanical type can usually be divided into two parts, the wind speed sensor and the wind direction sensor, while the ultrasonic type adopts an integrated structure. Different types of sensors have certain differences in their structure, characteristics, parameters, and principles.

1. Mechanical wind speed sensor

The wind speed sensor adopts a three-cup design structure, which is driven by the thrust generated by the air flow to drive the sensor to rotate rapidly, and the internal sensing element will generate a corresponding pulse signal. There is a certain linear relationship between wind speed and pulse frequency, and the current wind speed can be estimated by calculation. The mechanical wind direction sensor obtains wind direction information through the rotation of the wind direction arrow, and can usually be used to measure the near-ground wind direction.

2. Ultrasonic wind speed sensor

The sensor uses the ultrasonic time difference method to accurately measure the wind speed and direction. The propagation of ultrasonic waves in the air will be affected by the wind speed and direction. Under certain conditions, the propagation speed of ultrasonic waves in the air is measured corresponding to the wind speed function. Through this calculation method, the current wind speed and wind direction information can be obtained.

Ultrasonic is a cutting-edge measuring instrument. The integrated design in structure can overcome the defects of traditional mechanical sensors. The sensor can be widely used in agriculture, forest fire prevention, greenhouse, animal husbandry, meteorological scientific research and other fields.

The data measured by the wind speed and direction sensor can be uploaded to the cloud platform through the collector, which is convenient for people to view at any time.

Regardless of the type of sensor, remote data transmission can be achieved, and it can also be viewed and controlled through the host computer.
