PRODUCT DESCRIPTION
The YWDP-2 Weather Phenomena Sensor is a high-precision precipitation detection device independently developed by Jinzhou Sunshine. Designed for advanced meteorological applications, it is capable of accurately identifying various types of rain and snow, meeting the requirements for precise weather observation.
Utilizing high-precision laser technology, the sensor enables accurate detection of rainfall, snowfall, and hail. The product is designed and manufactured in accordance with the standards of the World Meteorological Organization (WMO), ensuring stable performance, high measurement accuracy, and unattended operation.
The YWDP-2 can classify a wide range of precipitation types, including:
drizzle, showers, rain, sleet, snow, snow pellets, freezing rain, and hail, covering comprehensive weather phenomena indicators.
Working Principle
The YWDP-2 Weather Phenomena Sensor operates based on the principle of light attenuation caused by precipitation particles crossing a laser beam. By utilizing advanced optical spectrum processing technology, it accurately measures the diameter, velocity, and distribution density of precipitation particles (liquid, solid, or mixed) as they pass through the detection area.
Combined with advanced data processing algorithms, the system analyzes key meteorological parameters such as precipitation intensity, accumulated rainfall, weather phenomena classification, and visibility. The sensor achieves an overall detection accuracy of over 95%.
With its multifunctional design, the YWDP-2 integrates the capabilities of a rain gauge, weather phenomenon sensor, and visibility sensor into a single device, enabling reliable all-weather, real-time meteorological monitoring.
