High precision small ultrasonic wind speed and direction sensor for measuring wind speed and direction

  Product overview Yifeng ultrasonic wind speed and direction sensor is a wind speed and direction measuring instrument developed based on the principle of ultrasonic
It uses the transmitted acoustic pulse to measure the time or frequency (Doppler transform) difference at the receiving end to calculate the wind speed and direction
The sensor can simultaneously measure the instantaneous value of wind speed and direction, and supports current and voltage signal output, RS485, Nb IOT, Lora, GPRS, Ethernet and other transmission modes
The shell of the whole machine is made of ABS, which has the characteristics of light weight, no moving parts, firmness and practicality, and does not need maintenance and on-site calibration
It can output wind speed and direction at the same time
It can be used with computer, data collector or other acquisition equipment with RS485 or analog output

⊙ working principle ultrasonic wind measurement is an application of ultrasonic detection technology in gas medium
It uses the propagation speed of ultrasonic in the air to be affected by air flow (wind) To measure the effect of wind speed
Compared with the conventional wind cup or rotor anemometer, the characteristic of this measurement method is that the whole wind measurement system has no mechanical rotating parts and belongs to inertial measurement, so it can accurately measure the high-frequency component of gust pulsation in natural wind

The ultrasonic wind speed and direction sensor uses four ultrasonic probes to send and receive ultrasonic waves circularly in the two-dimensional plane, and measures the wind speed and direction through the time difference of ultrasonic propagation in the air
