NBL-W-91GUWS 9-in-1 Ultrasonic Weather Station Sensor

The NBL-W-91GUWS 9-in-1 ultrasonic weather station sensor integrates wind speed, wind direction, air temperature, relative humidity, barometric pressure, rainfall, PM2.5, PM10 and one selectable light measurement parameter in one compact outdoor unit.

The ninth parameter can be configured as either solar radiation in W/m² or illuminance in Lux. Wind speed and wind direction are measured using ultrasonic transit-time technology with a wind speed range of 0–60 m/s, while rainfall is measured using piezoelectric raindrop impact detection.

The sensor also integrates PM2.5 and PM10 particulate matter monitoring and provides RS485 Modbus RTU communication for connection to compatible weather station data loggers, PLCs and IoT gateways. It is suitable for meteorological, agricultural, environmental, aviation, port, transportation and industrial monitoring systems.

9-in-1 Ultrasonic Weather Station Sensor Specifications

*Configuration note: Solar radiation and illuminance are alternative ninth parameters. Select one according to the monitoring requirement; they are not both included in the standard 9-in-1 configuration.

Nine Weather and Environmental Parameters in One Sensor

This 9-in-1 ultrasonic weather station sensor combines meteorological, rainfall, particulate matter and solar/light measurements in one compact device. It is designed for monitoring systems that require both weather data and basic ambient air-quality information from one installation point.

Ultrasonic Wind Speed and Direction Measurement

The ultrasonic wind measurement system compares the transit time of sound signals between opposing transducers. Airflow changes the signal travel time, allowing wind speed and wind direction to be calculated without conventional rotating wind cups or a mechanical wind vane.

The integrated ultrasonic wind sensor measures wind speed from 0 to 60 m/s with 0.01 m/s resolution, supporting meteorological, aviation, transportation, port and environmental monitoring systems.

Piezoelectric Rainfall Measurement

The rainfall channel uses piezoelectric ceramic kinetic detection. When raindrops strike the sensing surface, their impact produces signals that are processed to calculate rainfall.

Unlike a conventional tipping bucket rain gauge, the integrated rainfall sensor does not use a mechanical tipping mechanism. This allows rainfall measurement to be incorporated into the compact ultrasonic weather station sensor.

PM2.5 and PM10 Air-Quality Monitoring

The ultrasonic weather sensor with PM2.5 and PM10 combines meteorological measurements with particulate matter monitoring. PM2.5 represents fine airborne particles, while PM10 represents larger inhalable particulate matter.

For projects requiring regulatory-grade particulate measurements, reference-method equivalence, certified calibration or specific environmental compliance, provide these requirements before model selection.

Solar Radiation or Illuminance: Select One

The ninth parameter of the weather sensor can be configured as either solar radiation or illuminance. These are different physical measurements and should be selected according to the project requirement.

Key Features

Ultrasonic Weather Sensor RS485 Modbus Integration

The ultrasonic weather sensor with RS485 Modbus can connect to compatible automatic weather station data loggers, PLCs and IoT gateways. Weather, rainfall, particulate matter and solar/light measurements are available through the digital communication interface according to the selected configuration.

Ultrasonic Weather Station Sensor Dimensions

Installation Recommendations

Install the ultrasonic weather station sensor vertically in an open and representative location. The site should provide unobstructed airflow, direct rainfall exposure and suitable solar or light exposure according to the selected ninth parameter.

Weather and Environmental Monitoring System Integration

9-in-1 Ultrasonic Weather Station Sensor → RS485 Modbus RTU → Data Logger / PLC / IoT Gateway → Cloud Platform or Private Server

The sensor itself provides measurement data through RS485 Modbus RTU. Remote 4G, Ethernet, Wi-Fi or LoRaWAN transmission requires a compatible data logger or IoT gateway and is not provided directly by the sensor.

8-in-1 vs 9-in-1 Ultrasonic Weather Station Sensor

How to Select the Right 9-in-1 Weather Sensor Configuration

FAQ

Q1. What does the NBL-W-91GUWS 9-in-1 ultrasonic weather station sensor measure?

A1. It measures wind speed, wind direction, air temperature, relative humidity, barometric pressure, rainfall, PM2.5 and PM10, plus either solar radiation or illuminance.

Q2. Can the 9-in-1 sensor measure both solar radiation and illuminance?

A2. No. Solar radiation and illuminance are alternative ninth-parameter configurations. Select one when ordering.

Q3. What is the wind speed measurement range?

A3. Wind speed is measured from 0 to 60 m/s with a resolution of 0.01 m/s.

Q4. How is rainfall measured?

A4. The integrated rainfall channel uses piezoelectric raindrop impact detection rather than a conventional mechanical tipping bucket.

Q5. What are the PM2.5 and PM10 measurement ranges?

A5. PM2.5 is measured from 0 to 1000 µg/m³ and PM10 from 0 to 2000 µg/m³.

Q6. Does the NBL-W-91GUWS measure noise?

A6. The standard 9-in-1 configuration on this page does not include noise. It includes rainfall and PM2.5/PM10 together with either solar radiation or illuminance.

Q7. Does the ultrasonic weather sensor support RS485 Modbus RTU?

A7. Yes. It provides RS485 Modbus RTU communication at 9600 bps for connection to compatible data loggers, PLCs and IoT gateways.

Q8. Is solar radiation the same as PAR or illuminance?

A8. No. Solar radiation is measured in W/m², illuminance in Lux and PAR/PPFD in µmol/m²/s. A dedicated PAR sensor is required for PPFD measurement.

Q9. Does the sensor include built-in 4G, Wi-Fi or LoRaWAN?

A9. No. The sensor itself provides RS485 measurement data. Remote communication requires a compatible data logger or IoT gateway.

Q10. Is the 9-in-1 sensor suitable for agricultural and environmental monitoring?

A10. Yes. It combines weather, rainfall, particulate matter and solar or light measurements, making it suitable for agricultural, meteorological and distributed environmental monitoring systems.

Quotation and Model Selection

For quotation and model selection, specify whether the ninth parameter should be solar radiation or illuminance, together with the required quantity, power supply, cable length, installation environment and the PLC, data logger or IoT gateway that will receive the RS485 Modbus data. If noise, PAR, regulatory particulate monitoring or additional environmental parameters are required, include them with the inquiry so the appropriate integrated weather sensor configuration can be selected.
