The All - Round Upgrade of Ultrasonic Weather Stations: Function, Performance and Application

The ultrasonic weather station emits continuous variable - frequency ultrasonic signals and detects wind speed and direction by measuring the relative phase. This enables it to get rid of the dependence on high - precision timers and solve the problem of inaccurate measurement caused by sensor start - up delay, demodulation circuit delay, and temperature changes. Moreover, it adopts non - contact measurement. Based on the difference in the propagation speed of ultrasonic waves in the air, it accurately calculates the round - trip time to obtain wind speed and direction data, avoiding the errors caused by mechanical wear or electronic interference in traditional measurement methods.

In terms of functions, there has also been a significant improvement. It has evolved from only being able to measure basic meteorological elements to an integrated sensor that can real - time observe as many as twelve meteorological elements, including wind speed, wind direction, temperature, humidity, air pressure, optical rainfall, PM2.5, PM10, CO, NO2, SO2, and O3. At the same time, the data processing is intelligent. It can automatically collect a variety of meteorological parameters and transmit them to the central server or cloud database at preset time intervals, which is convenient for remote monitoring and analysis.

It has a faster response speed and can almost instantly feedback meteorological information, completing the measurement of wind speed and direction in a short time. Its environmental adaptability has been enhanced. The device is equipped with waterproof, dust - proof, and lightning - protection measures. The sensor housing is made of imported ASA material, and the protection level reaches above IP65, enabling it to work normally in various harsh environments. In addition, the power consumption is reduced. The highly integrated structure reduces the dependence on external energy sources, which is conducive to stable operation using solar power.

The appearance adopts an integrated and compact design. Multiple sensors are integrated into a small device, saving space and being convenient for installation and portability. There is also a hidden probe design, such as a hidden ultrasonic probe in the top cover, which avoids the accumulation of rain and snow and the blockage of natural wind, ensuring the accuracy of measurement.

There are various transmission methods. GPRS is standard - equipped, and RJ45, Ethernet, 4 - 20ma, Lora transparent transmission, 4G transparent transmission, Bluetooth, 485 - to - USB, etc. are also optional. It is equipped with powerful host computer software, an Android APP, and a cloud platform, supporting multi - account and multi - device logins. It can be directly observed on mobile phones and PC browsers, and supports functions such as real - time and historical data display, data curve analysis, and data export.

These upgrades will enable it to play a more important and efficient role in meteorological monitoring, providing more reliable data support for meteorological research, disaster early warning, etc.
