Application Case of 7-in-1 Ultrasonic Multi-Parameter Weather Sensor

New Standard for Integrated Meteorological Monitoring — Precise Performance of Niubol 7-in-1 Ultrasonic Weather Sensor in Complex Industrial and Environmental Monitoring Scenarios 

 I. Project Background: Practical Demands for Multi-Parameter Monitoring 

In scenarios involving smart meteorology and industrial environmental monitoring, single meteorological parameters can no longer meet modern application needs.  

For example, in factories, ports, scientific research bases, and smart agricultural parks, factors such as wind speed, wind direction, temperature and humidity, pressure, rainfall, and solar radiation often interact with each other, directly impacting equipment safety, environmental assessments, energy regulation, and production strategies.  

To meet these complex application demands, Niubol has launched the 7-in-1 Ultrasonic Wind Speed and Direction Multi-Parameter Weather Sensor (NBL-W-71GUWS).  

This device is designed with high integration, maintenance-free operation, and digital output as its core principles, fusing multiple key meteorological elements into a compact structure to achieve precise and efficient environmental data collection.

 II. Device Overview: High-Integration Multi-Element All-in-One Design 

The Niubol 7-in-1 Ultrasonic Weather Sensor is a fully digital, high-precision, multi-parameter monitoring device.  

It can simultaneously detect seven elements:  

Wind speed, wind direction, atmospheric temperature, atmospheric humidity, atmospheric pressure, rainfall, and solar radiation.  

Additionally, it can be optionally equipped with PM2.5, PM10, noise, and other sensor modules to adapt to more complex urban environments and smart ecological projects.  

The device features a compact structure, high integration, and IP65 protection rating, making it suitable for extreme weather, coastal environments, high-humidity factories, scientific research sites, transportation hubs, and other complex scenarios.

 III. Description of Each Monitoring Parameter and Its Functions 

The following outlines the functions of each element within the sensor and their significance in practical applications: 

1. Wind Speed and Wind Direction  

   Wind speed and direction are direct reflections of atmospheric motion, which are crucial for industrial ventilation, pollutant diffusion analysis, port scheduling, and more.  

   Niubol employs ultrasonic time-of-flight difference measurement technology, calculating wind speed and direction by comparing the propagation time differences in the N-S and E-W directions.  

   Advantages:  

   - No mechanical structure, maintenance-free;  

   - Fast response and strong anti-interference;  

   - Unaffected by temperature or humidity;  

   - Suitable for long-term unmanned operation. 

2. Temperature and Humidity  

   These two data points are foundational indicators affecting equipment operation, personnel comfort, and air quality.  

   The temperature and humidity module uses high-precision digital probes, capable of stable operation in the -40°C to 80°C range, with output errors below ±0.5°C and ±5% RH.  

   In agriculture, warehousing, energy, and transportation sectors, temperature and humidity data are commonly used for automatic ventilation, dehumidification, air conditioning control, and energy balance management. 

3. Pressure  

   Pressure changes are often closely related to weather system evolution, wind speed variations, and more.  

   By monitoring pressure, it assists in predicting storms, rainfall, or sudden meteorological events.  

   In industrial applications, pressure data is also used for ventilation and pressure compensation control in enclosed spaces. 

4. Rainfall  

   It employs a piezoelectric ceramic kinetic rainfall detection principle.  

   When raindrops strike the sensing surface, the piezoelectric element converts kinetic energy into an electrical signal, calculating rainfall intensity and cumulative rainfall based on signal amplitude and frequency.  

   Advantages:  

   - Highly sensitive, capable of identifying from light rain to heavy rain;  

   - No mechanical tipping bucket structure, maintenance-free;  

   - Resistant to freezing jams and dust accumulation errors.  

   Rainfall monitoring has direct significance for flood warnings, irrigation control, and drainage system optimization. 

5. Solar Radiation  

   The solar radiation sensing module can measure light intensity from 0 to 1500 W/m², with an error less than 10%.  

   In smart agriculture, solar power plants, and building energy-saving analysis projects, radiation data serves as a key parameter for calculating light utilization rates, evapotranspiration, and energy balance. 

 IV. Detailed Working Principles 

The wind speed and direction section uses the ultrasonic time-of-flight difference method.  

The sensor measures the propagation time differences of ultrasonic waves from N→S and S→N, E→W and W→E, and calculates wind speed and direction through algorithms, without relying on temperature compensation.   

The rainfall section employs the piezoelectric kinetic energy measurement method:  

When raindrops strike the piezoelectric sheet at a constant terminal velocity, the sensor infers the weight of individual raindrops and rainfall intensity through impact force (P = mv).  

Compared to traditional tipping bucket rain gauges, it offers advantages such as fast response, no mechanical wear, and no need for cleaning. 

 V. Technical Specifications Overview 

 VI. Installation Notes 

To ensure measurement accuracy and long-term reliability, adhere to the following key points during installation:  

1. Avoid Interference Sources: Stay away from strong interference devices such as radio transmitters, radars, engines, etc.;  

2. Installation Location: Position in open, unobstructed areas, avoiding buildings, trees, or other obstacles that could generate turbulence;  

3. Anti-Vibration Measures: Keep away from mechanical vibration sources and ensure the mounting tube is stable;  

4. Direction Calibration: Use a standard compass during installation to align the sensor's north indicator with true geographic north;  

5. Mounting Tube Requirements: The tube top should be 7.5 mm from the screw hole, secured with M5 screws;  

6. Cable Handling: Cables should include stress relief, with tight connections and shielded wires grounded as instructed;  

7. Continuous Power Supply: Maintain stable power input to avoid power outages or transient voltage fluctuations;  

8. Regular Inspections: Prevent external debris from obstructing measurement ports.  

Proper installation not only affects wind speed and direction measurement accuracy but also ensures overall data consistency and reliability. 

 VII. Application Scenarios and Effects 

The Niubol 7-in-1 sensor has been successfully applied in multiple projects:  

- Smart Factory Environmental Monitoring: Real-time capture of wind direction, humidity, and rainfall changes to provide basis for ventilation and safety management;  

- Agricultural Weather Stations: Integration with irrigation systems for smart irrigation and evapotranspiration control;  

- Solar Power Plants: Dynamic optimization of power generation efficiency based on radiation and temperature data;  

- Urban Air Monitoring Stations: Paired with PM2.5 and PM10 modules for refined environmental data collection.  

Through these practical applications, the device demonstrates significant advantages in high precision, high stability, and low maintenance costs, making it an ideal choice for multi-field meteorological monitoring.

 VIII. Summary 

The Niubol 7-in-1 Ultrasonic Multi-Parameter Weather Sensor integrates seven core meteorological elements into one unit, utilizing advanced ultrasonic and digital detection technologies. It features a compact structure, maintenance-free operation, standardized communication, and easy installation.  

It not only enhances the efficiency and data quality of meteorological monitoring but also provides reliable data support for industrial automation, smart agriculture, and environmental governance.
