NBL-W-61MUWS 6-in-1 Ultrasonic Weather Station Sensor with Rainfall

The NBL-W-61MUWS 6-in-1 ultrasonic weather station sensor integrates wind speed, wind direction, air temperature, relative humidity, barometric pressure and rainfall measurement in one compact outdoor sensor.

Wind speed and wind direction are measured using ultrasonic transit-time technology, while rainfall is detected using a piezoelectric kinetic rainfall sensor. Temperature, humidity and atmospheric pressure are measured simultaneously, allowing six 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. It is suitable for agricultural weather stations, environmental monitoring, ports, transportation, industrial sites and distributed meteorological monitoring systems.

6-in-1 Ultrasonic Weather Station Sensor Specifications

Six Weather Parameters in One Sensor

The NBL-W-61MUWS is a wind speed direction temperature humidity pressure rainfall sensor designed for projects that require six core meteorological measurements from one compact monitoring point.

Wind Speed

Measures wind velocity from 0 to 40 m/s using ultrasonic transit-time technology.

Wind Direction

Measures wind direction from 0 to 359° without a conventional mechanical wind vane.

Air Temperature

Provides ambient air temperature data for weather and environmental monitoring.

Relative Humidity

Measures atmospheric moisture conditions from 0 to 100% RH.

Barometric Pressure

Provides atmospheric pressure measurements for meteorological monitoring systems.

Rainfall

Uses piezoelectric impact detection to measure rainfall without a conventional tipping bucket mechanism.

Ultrasonic Wind and Piezoelectric Rainfall Measurement

Ultrasonic Wind Measurement

Wind speed and direction are calculated by comparing the transit time of ultrasonic signals traveling between opposing transducers. Airflow changes the ultrasonic travel time in different directions, allowing the sensor to calculate wind velocity and direction without rotating wind cups or a mechanical vane.

Piezoelectric Rainfall Measurement

The integrated rainfall channel uses piezoelectric ceramic kinetic detection. When raindrops strike the sensing surface, the sensor detects the impact generated by the droplets and uses this information to calculate rainfall.

Unlike a traditional tipping bucket rain gauge, piezoelectric rainfall measurement does not require a mechanical tipping mechanism. This makes it useful where a compact integrated weather sensor is preferred.

Ultrasonic Weather Sensor Key Features

6-in-1 Measurement

Six meteorological parameters are integrated into one compact outdoor sensor.

Ultrasonic Wind Measurement

Wind speed and direction are measured without conventional rotating wind cups or vanes.

Piezoelectric Rainfall

Rainfall is detected from raindrop impact using piezoelectric kinetic measurement.

RS485 Modbus RTU

Provides digital integration with compatible PLCs, weather data loggers and IoT gateways.

Low Power Consumption

Low average power demand is suitable for distributed weather monitoring systems.

IP65 Protection

Designed for outdoor meteorological and environmental monitoring installations.

RS485 Modbus RTU Integration

The ultrasonic weather sensor with RS485 Modbus can connect to compatible PLCs, data loggers and IoT gateways. The sensor provides digital meteorological data that can then be stored locally or transmitted to a cloud platform or private server by the connected communication equipment.

Wiring

Confirm the cable label and wiring before applying power. When several Modbus devices share one RS485 bus, each sensor should use a unique communication address.

Typical Weather Monitoring System

NBL-W-61MUWS → RS485 Modbus RTU → Data Logger / PLC / IoT Gateway → Cloud Platform or Private Server

The NBL-W-61MUWS itself provides weather measurement data through RS485. Remote communication through 4G, Ethernet, Wi-Fi or LoRaWAN requires a compatible data logger or IoT gateway with the required communication function.
