[October 28, 2024] — Today, an innovative rainfall monitoring device based on optical principles was officially launched. Using laser scattering technology for precise identification of precipitation particles, this sensor redefines modern rainfall monitoring standards with 0.1mm resolution and 99% data accuracy, providing a new generation technical solution for weather forecasting, smart cities, flood warning, and other fields.
I. Industry Pain Points: Limitations of Traditional Rainfall Monitoring
Mechanical tipping bucket rain gauges have long faced numerous challenges:
- Mechanical Wear: Tipping bucket structure prone to aging, causing long-term monitoring data drift
- Susceptible to Blockage: Debris like leaves and dust can affect bucket movement
- Frequent Maintenance: Requires regular calibration and cleaning, resulting in high operational costs
- Limited Accuracy: Significant errors during extreme weather conditions like strong winds and heavy rain
II. Technological Breakthrough: Core Advantages of Optical Rainfall Sensors
1. Optical Measurement Principle
- Uses laser scattering + particle imaging technology to distinguish precipitation types like rain, snow, and hail
- Measurement range: 0-200mm/h
- Resolution: 0.1mm
- Sampling frequency: Real-time analysis 10 times per second
2. All-Solid-State Design
- No moving parts, fundamentally avoiding mechanical wear
- IP68 protection rating, stable operation in harsh environments like dust and salt fog
- Operating temperature: -40℃ to 70℃
3. Intelligent Functions
- Built-in AI algorithm automatically filters non-precipitation interference like insects and leaves
- Supports 5G/NB-IoT wireless transmission for real-time cloud data upload
- Solar + lithium battery power supply, continuous operation for 30 days in cloudy weather
III. Field Test Data: Significant Results in Multiple Scenarios
1. Weather Station Application
In comparative tests at a coastal meteorological station:
- Data consistency with traditional tipping bucket rain gauges reached 99.2%
- Successfully monitored 500mm/24h extreme rainstorm during typhoon conditions
- Maintenance cycle extended from 1 month to 1 year
2. Smart City Application
- Installed in urban low-lying areas, successfully warned of 3 waterlogging risks
- Integrated with drainage systems, warning response time shortened to 10 minutes
- Achieved fully automated ”rainfall-waterlogging-dispatch” management
IV. Application Prospects
The sensor has obtained China Meteorological Administration Equipment Access Certification and CE/ROHS International Certification, suitable for:
- Meteorology and Hydrology: National automatic weather stations, flood warning platforms
- Smart Cities: Urban waterlogging monitoring, road warning
- Traffic Management: Highway and airport runway weather monitoring
- Agricultural Irrigation: Precision agriculture precipitation data support
