Multi element ultrasonic meteorological stationIt is a high-precision meteorological monitoring device based on ultrasonic technology, which adopts an integrated design and integrates multiple element sensors such as wind speed, wind direction, temperature, humidity, air pressure, and rainfall. The device does not require mechanical moving parts and achieves data acquisition through non-contact measurement. It has the characteristics of low power consumption, fast installation, and strong environmental adaptability, and is suitable for long-term unmanned outdoor scenarios. Its shell is mostly made of corrosion-resistant materials (such as imported ASA material), with high protection level, which can resist harsh environments such as salt spray, rain and snow.
core principle
Unlike traditional mechanical anemometers, ultrasonic weather stations use the ultrasonic time difference method to measure wind speed and direction
Transmit and receive sound waves between two or more ultrasonic probes.
In the absence of wind, the round-trip time of sound waves is the same; When there is wind, sound waves propagate faster in the downwind direction and slower in the upwind direction.
Calculate the three-dimensional wind speed and direction based on the time difference of sound wave propagation.
No need to rotate parts, achieving mechanical wear free and maintenance free operation.
Main monitoring parameters
Wind speed (m/s) - measured by ultrasonic sensor
Wind direction (°) - measured by ultrasonic sensor
Air temperature (℃)
Relative humidity (% RH)
Atmospheric pressure (hPa)
Precipitation (mm) - optional tipping bucket or optical rain gauge
Solar radiation (W/m ²) - optional illumination or total radiation sensor
PM2.5/PM10 (optional) - for air quality monitoring
Note: Some models can also integrate sensors such as noise, CO ₂, visibility, etc. to achieve multifunctional environmental monitoring.
