Classification Principle and Application of Wind Direction and Wind Speed Sensors
1. Principle of wind speed sensor--Introduction
The wind speed sensor is mainly made of high-quality aluminum alloy profile, which is electroplated and sprayed on the surface. It has good anti-corrosion and anti-corrosion characteristics, which can effectively ensure that the long-term use of the instrument will not rust, and at the same time cooperate with the internal smooth bearing system. Used together to ensure the accuracy of the collected information. The wind speed sensor is an intelligent instrument with easy to use, good performance and high reliability. It can be widely used to measure the wind speed in greenhouses, environmental protection, weather stations and breeding places.
2. Principle of wind speed sensor - classification
There are many types of wind speed sensors, which can be mainly divided into pitot tube wind speed sensors, propeller wind speed sensors, Hall effect electromagnetic wind speed sensors, hot wire wind speed sensors and ultrasonic wind speed sensors.
Next, the editor of Gongcai.com will briefly introduce the ultrasonic wind speed sensor and the propeller wind speed sensor.
3. Principle of wind speed sensor--ultrasonic wind speed sensor
The ultrasonic wind speed sensor mainly uses the ultrasonic time-of-flight method to measure the wind speed. The speed of sound propagation in the air will be superimposed with the airflow speed in the wind direction. If the ultrasonic wave travels in the same direction as the wind, its speed will increase; otherwise, its speed will slow down. Therefore, under fixed detection conditions, the speed of ultrasonic waves propagating in the air can correspond to the wind speed function. Accurate wind speed and wind direction can be obtained through calculation.

4. Principle of wind speed sensor--propeller wind speed sensor
The propeller wind speed sensor is mainly composed of propeller blades, sensor shaft, sensor bracket and magnetic induction coil. It uses the kinetic energy of the flowing air to drive the propeller of the sensor to rotate, and then obtains the air flow rate through the terminal device through the speed of the propeller.
