NBL-W-51MUWS 5-in-1 Ultrasonic Weather Station Sensor

The NBL-W-51MUWS 5-in-1 ultrasonic weather station sensor integrates wind speed, wind direction, air temperature, relative humidity and barometric pressure measurement in one compact outdoor sensor.

Wind speed and wind direction are measured using ultrasonic transit-time technology without conventional rotating wind cups or a mechanical wind vane. Temperature, humidity and atmospheric pressure are measured simultaneously, allowing five basic meteorological parameters to be collected from a single installation point.

With RS485 Modbus RTU communication, the sensor can connect to compatible weather station data loggers, PLCs and IoT gateways for agriculture, automatic weather stations, environmental monitoring, ports, transportation and distributed outdoor monitoring systems.

What Does the 5-in-1 Weather Sensor Measure?

The NBL-W-51MUWS is a wind speed direction temperature humidity pressure sensor designed to provide five core meteorological measurements through one integrated device.

How Ultrasonic Wind Measurement Works

The sensor measures wind using ultrasonic transit time. Ultrasonic signals travel between opposing transducers, and airflow changes the travel time of these signals. The difference in transit time is used to calculate wind speed and wind direction.

Unlike conventional cup anemometers and wind vanes, the ultrasonic wind measurement section does not depend on rotating mechanical components. This reduces mechanical wear and simplifies long-term operation in distributed outdoor weather monitoring systems.

Key Features

5-in-1 Measurement

Wind speed, wind direction, temperature, humidity and pressure are integrated into one sensor.

Ultrasonic Wind Measurement

Wind measurement does not require conventional rotating cups or a mechanical wind vane.

RS485 Modbus RTU

Connects to compatible PLCs, weather data loggers and IoT gateways.

Low Power Consumption

Average power consumption of approximately 0.3 W supports low-power monitoring systems.

IP65 Protection

Suitable for outdoor weather and environmental monitoring installations.

Compact Installation

Five meteorological parameters are collected from one mounting position.

RS485 Modbus RTU Integration

The ultrasonic weather sensor with RS485 Modbus can be integrated with compatible weather station data loggers, PLCs and IoT gateways. All five meteorological measurements are available through one RS485 communication interface.

When multiple compatible Modbus sensors share one RS485 bus, configure a unique communication address for each device and allow a suitable polling interval between commands.

Typical Weather Monitoring System

NBL-W-51MUWS → RS485 Modbus RTU → Data Logger / PLC / IoT Gateway → Cloud Platform or Private Server

The sensor itself provides meteorological measurements through RS485. Remote communication through 4G, Ethernet, Wi-Fi or LoRaWAN requires a compatible data logger or communication gateway.

Sensor Dimensions

The integrated housing reduces the number of separate sensor brackets and mounting positions required for five basic meteorological measurements.

FAQ

Q1. What does the NBL-W-51MUWS 5-in-1 ultrasonic weather station sensor measure?

A1. It measures wind speed, wind direction, air temperature, relative humidity and barometric pressure in one integrated device.

Q2. What is the wind speed measurement range?

A2. The wind speed measurement range is 0–40 m/s with a resolution of 0.01 m/s.

Q3. How does the ultrasonic weather sensor measure wind?

A3. The sensor compares the transit time of ultrasonic signals between opposing transducers. Changes in signal travel time caused by airflow are used to calculate wind speed and direction.

Q4. Does the NBL-W-51MUWS support RS485 Modbus?

A4. Yes. The sensor supports RS485 communication using Modbus RTU at 9600 bps.

Q5. Can it connect to a PLC or data logger?

A5. Yes. A compatible PLC, weather station data logger or IoT gateway with an RS485 Modbus RTU interface can read the five meteorological measurements.

Q6. Does the sensor need to be aligned with north?

A6. Yes. The north reference mark should be aligned with geographic north during installation so that wind direction measurements correspond correctly to compass direction.

Q7. Is it suitable for agricultural weather stations?

A7. Yes. It provides five basic meteorological parameters for agricultural monitoring. Rainfall, solar radiation, PAR and soil measurements require additional sensors if the project requires those parameters.

Q8. Does the NBL-W-51MUWS measure rainfall?

A8. No. This model measures wind speed, wind direction, temperature, humidity and barometric pressure. Rainfall requires an additional rain sensor or another integrated weather sensor configuration that includes rainfall measurement.

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

A9. No. The sensor provides RS485 data. Remote communication through 4G, Wi-Fi, Ethernet or LoRaWAN requires a compatible data logger or IoT gateway.

Q10. Can several RS485 sensors share one bus?

A10. Yes. Multiple compatible Modbus devices can share one RS485 bus when each device is assigned a unique address and the communication network is wired and configured correctly.

Quotation and Model Selection

For quotation and system integration, specify the required quantity, power supply, cable length, installation location and the PLC, data logger or IoT gateway that will receive the RS485 Modbus data. If the project also requires rainfall, solar radiation, PAR, soil sensors, remote 4G communication or a complete automatic weather station, include these requirements with the inquiry.
