  The principle of the wind speed sensor -- the wind speed sensor mainly adopts the high-quality aluminum alloy profile, which is electroplated and sprayed on the surface. It has good anti-corrosion and anti-corrosion characteristics, it can effectively ensure the long-term use of the instrument does not rust, while the internal smooth bearing system together to ensure that the collection of sourcing circumstances. Wind speed sensor is a kind of intelligent instrument with convenient use, good performance and high reliability. It can be widely used to measure wind speed in greenhouse, environmental protection, weather station and breeding place. 2. Principle of wind speed sensor -- classification there are many kinds of wind speed sensors, mainly can be divided into pitot-tube wind sensor, propeller wind sensor, Hall Effect Electromagnetic Wind Sensor, hot-wire wind sensor and ultrasonic wind sensor. 3. Principle of wind speed sensor-ultrasonic wind speed sensor mainly uses ultrasonic time difference method to measure wind speed. The speed of sound in the air will be superimposed with the air speed in the wind direction. If the ultrasonic wave travels in the same direction as the wind, it will speed up; if it travels in the opposite direction, it will slow down. Therefore, under the fixed detection conditions, the velocity of ultrasonic wave in the air can correspond to the function of wind speed. Accurate wind speed and direction can be obtained by calculation. 4. Principle of wind speed sensor-propeller wind speed sensor is mainly composed of propeller blade, sensor shaft, sensor support and magnetic induction coil. It uses the kinetic energy of flowing air to drive the sensor's propeller to rotate, and then uses the propeller's speed to calculate the air velocity flowing through the terminal device. According to reports, Hitachi produced by the development of this new sensor using semiconductor technology, can be due to compression of the deformation of objects into a signal. Its size is only 2.5 mm 2.5 mm 0.2 mm, to achieve ultra-miniaturization, can be installed in any parts. Therefore, it can be attached to the surface of the object can be measured changes in shape, under the pressure and vibration of a variety of data. The sensor has 25,000 times the sensitivity of a conventional material strength gauge, can detect subtle changes in component shape and is more energy efficient. For example, if the sensor is mounted on the part of a car engine, the internal pressure can be used to determine how much gasoline is most suitable for injection. Because of its large volume, traditional measuring instrument is difficult to be installed in automobile. By miniaturizing the sensor, Hitachi has greatly expanded its application range.
