Product Description
RS485 Ultrasonic wind speed and direction sensor for weather station and agriculture
1.1 Product overview
The small ultrasonic wind speed and direction sensor is a wind speed and direction measuring instrument developed based on the principle of ultrasonic waves. It uses the transmitted sound wave pulse to measure the phase difference at the receiving end to calculate the wind speed and direction. The sensor can measure the instantaneous value of wind
The small ultrasonic wind speed and direction sensor is a wind speed and direction measuring instrument developed based on the principle of ultrasonic waves. It uses the transmitted sound wave pulse to measure the phase difference at the receiving end to calculate the wind speed and direction. The sensor can measure the instantaneous value of wind
speed and wind direction at the same time, and is widely used in the measurement of wind speed and wind direction in the fields of meteorology, ocean, environment, airports, ports, laboratories, industry, agriculture, and transportation.

1.4 Working principle
Ultrasonic wind measurement is an application of ultrasonic detection technology in gaseous media. It uses the influence of air flow (wind) to measure wind speed by using the propagation speed of ultrasonic waves in the air. Compared with conventional wind cups or rotary wing anemometers, the biggest feature of this measurement method is that the entire wind measurement system does not have any mechanical rotating parts, which is a non-inertial measurement, so it can accurately measure the high frequency components of gusts in natural wind.
The ultrasonic wind speed and direction transmitter uses four ultrasonic probes to send and receive ultrasonic waves in a two-dimensional plane.
The principle of the increase and decrease of ultrasonic waves affected by wind speed is used to realize the measurement of wind speed and wind direction.

This product can also be used in combination with multiple sensors on a 485 bus. In theory, one bus can be used with 254 485 sensors, and the other end is connected to a PLC with a 485 interface, and a single-chip microcomputer is connected through the 485 interface chip, or USB to 485 can be used to connect with Computer connection, use the sensor
configuration tool provided by our company to configure and test (only one device can be connected when using the configuration software).
