​Rainfall & Precipitation Measurement — Rain Gauge, Tipping Bucket Rain Sensor

NiuBoL Rainfall Monitoring Solution  

I. Application Background: The Critical Value of Rainfall Data 

Rainfall is a core indicator in meteorological and hydrological monitoring, directly influencing agricultural production, flood control scheduling, and urban drainage. 

- Agriculture: Rainfall data enables farmers to optimize irrigation schedules, preventing water waste from over-irrigation or crop loss from drought. It boosts water efficiency and yields. Modern smart agriculture integrates precise rainfall with crop water demand models for scientific, water-saving farming.  

- Hydrology & Flood Control: Real-time rainfall is the foundation for flood risk forecasting and reservoir management. Abnormal rainfall peaks can trigger river overflow; delayed monitoring risks property damage and casualties.  

- Municipal Management: Rainfall monitoring at flood-prone urban points, underpasses, and low-lying roads supports inner-city flood prevention, drainage optimization, and emergency response. With increasing urban impervious surfaces and extreme weather, real-time data is indispensable for smart city resilience. 

Traditional manual observation or basic devices suffer from high error, data lag, and maintenance challenges. To address this, NiuBoL launches a full-scenario intelligent rainfall monitoring system, achieving a closed-loop process: sensing → transmission → analysis → alerting → control, meeting diverse needs in agriculture, hydrology, and municipal sectors. 

 II. Industry Pain Points & Solution Directions 

- Inaccurate Data: Simple rain gauges are severely affected by wind, debris, or blockages → errors >20%, failing precision management.  

- Delayed Response: Manual logging or single-point delayed uploads miss critical flood or irrigation decision windows.  

- Poor Environmental Adaptability: High heat, salt fog, or dust cause jamming, corrosion, or sensor failure.  

- Data Silos: Multi-point deployments lack unified platforms → no trend analysis or decision support. 

NiuBoL optimizes across four dimensions: high-precision sensing, reliable communication, environmental resilience, and platform intelligence.

 V. Implementation & Application Scenarios 

 5.1 Agricultural Irrigation

Deploy NBL-W-DRS in fields → system auto-collects rainfall and analyzes with crop water models.  

When cumulative rainfall hits threshold → “Pause Irrigation” alert + auto-shutoff pump → precise water savings and higher yields.  

Integrate with soil moisture sensors → optimize irrigation volume.  

Use historical data to adjust sowing plans and crop varieties, reducing climate risk.

  5.2 Hydrological Flood Prevention

Multi-point deployment (upstream, midstream, downstream) → LoRa mesh to central node → 4G to cloud.  

When hourly intensity >20 mm → auto “Flood Alert” to downstream teams → pre-deploy defenses, close gates, activate drainage.  

Cloud + river flow models → predict flood zones for reservoir scheduling and urban planning. 

 5.3 Municipal Drainage

Link sensors with water level gauges → monitor rainfall + water depth.  

When >30 mm/h + water level exceeds alert → auto-start drainage pumps + alert to duty staff (response <5 min).  

City-wide flood-point rainfall map → optimize pipe network design and smart emergency dispatch. 

 5.4 Smart Cities & Research
