YD1 Raindrop Sensor: An All - in - One Solution for Precipitation Monitoring

The YD1 Raindrop Sensor is an intelligent sensor that integrates precipitation particle spectrum monitoring and weather phenomenon identification. By actively emitting an infrared light band, the instrument can capture in real-time the changes in light energy when precipitation particles pass through the light band, and accurately calculate the falling speed and size distribution of the particles. Combining with empirical models, this device can automatically determine the types of precipitation (such as drizzle, rain, sleet, snow, hail, etc.), providing accurate data support for meteorological observations.

Technical Features:

Integrated design with a compact structure (660×450×120mm, weight ≤ 7kg), making it easy to install and deploy.

High environmental adaptability, with an operating temperature range from -40°C to 50°C and a protection level of IP65, capable of adapting to extreme climatic conditions.

Anti-pollution design. The transmitting and receiving ends are equipped with splash-proof covers to prevent precipitation particles from interfering with the sampling area.

Data visualization. Professional software can be optionally selected to display the raindrop spectrum distribution in a graphical form.

Calibration compatibility. A calibration device can be optionally selected to ensure the measurement accuracy during long-term operation.
