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

The NBL-W-61GUWS 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 unit.

Wind speed and wind direction are measured using ultrasonic transit-time technology with a measurement range up to 60 m/s. Rainfall is measured using piezoelectric raindrop impact detection, while integrated digital sensors simultaneously measure temperature, humidity and atmospheric pressure.

The sensor provides RS485 Modbus RTU communication for connection to compatible automatic weather station data loggers, PLCs and IoT gateways. It is suitable for agriculture, environmental monitoring, airports, ports, transportation, industrial sites and distributed meteorological monitoring systems.

Six Meteorological Parameters in One Weather Sensor

This wind speed direction temperature humidity pressure rainfall sensor combines six core meteorological measurements in one compact device, reducing the number of separate instruments, mounting brackets and communication connections required at one monitoring site.

How the Ultrasonic Weather Station Sensor Measures Wind

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

The 0–60 m/s ultrasonic wind sensor provides 0.01 m/s resolution and is suitable for projects requiring a wider wind measurement range in a compact integrated weather monitoring unit.

Piezoelectric Rainfall Measurement

The integrated rainfall sensor uses piezoelectric ceramic kinetic detection. When raindrops strike the sensing surface, their impact generates a signal that is processed to determine rainfall.

This design does not use the mechanical tipping mechanism found in a conventional tipping bucket rain gauge, allowing rainfall measurement to be integrated directly into the 6-in-1 ultrasonic weather station sensor.

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. The communication interface provides access to wind speed, wind direction, temperature, humidity, pressure and rainfall data.

Available Modbus Measurement Data

The sensor provides both accumulated rainfall and real-time rainfall values through the Modbus data frame. Accumulated rainfall can also be reset when required by the monitoring system.

Wiring

Use the markings on the supplied communication cable as the final wiring reference. Complete all wiring and verify power polarity and RS485 A/B connections before applying power.

Ultrasonic Weather Station Sensor Dimensions

Installation Recommendations

Install the ultrasonic weather station sensor vertically in an open location with representative airflow and unobstructed rainfall exposure. Correct north alignment is required for wind direction measurement.

Automatic Weather Station System Integration

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

The sensor provides meteorological measurements through RS485 Modbus RTU. Remote transmission through 4G, Ethernet, Wi-Fi or LoRaWAN requires a compatible data logger or IoT gateway; these communication functions are not built into the sensor itself.

How to Select the Right Ultrasonic Weather Station Sensor

FAQ

Q1. What does the NBL-W-61GUWS 6-in-1 ultrasonic weather station sensor measure?

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

Q2. What is the wind speed measurement range?

A2. The ultrasonic wind speed range is 0–60 m/s with a resolution of 0.01 m/s.

Q3. How does the 6-in-1 weather sensor measure rainfall?

A3. Rainfall is measured by piezoelectric raindrop impact detection. The sensor detects the impact of falling raindrops and processes these signals to calculate rainfall.

Q4. Does it provide accumulated and real-time rainfall?

A4. Yes. The Modbus data includes accumulated rainfall and real-time rainfall values, both with 0.01 mm resolution.

Q5. Does the ultrasonic weather sensor support RS485 Modbus RTU?

A5. Yes. It provides RS485 Modbus RTU communication at 9600 bps for integration with compatible data loggers, PLCs and IoT gateways.

Q6. Can it connect directly to a weather station data logger?

A6. Yes. A compatible weather station data logger or controller with an RS485 Modbus RTU interface can read the six meteorological parameters.

Q7. Does this model measure illuminance or solar radiation?

A7. The standard 6-in-1 configuration measures wind speed, wind direction, temperature, humidity, pressure and rainfall. Projects requiring illuminance or solar radiation should select the appropriate higher-parameter model or add a dedicated sensor.

Q8. Does the sensor require north alignment?

A8. Yes. Align the north reference point with geographic north during installation so the reported wind direction corresponds correctly to compass direction.

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

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

Q10. What is the difference between NBL-W-51GUWS and NBL-W-61GUWS?

A10. Both measure wind speed, wind direction, temperature, humidity and barometric pressure with a 0–60 m/s wind range. The NBL-W-61GUWS additionally integrates piezoelectric rainfall measurement.

Quotation and Model Selection

For quotation and model selection, specify the required wind speed range, rainfall requirement, quantity, power supply, cable length, installation environment and the PLC, data logger or IoT gateway that will receive the RS485 Modbus data. If illuminance, solar radiation, particulate matter, noise or other parameters are required, include them with the inquiry so the appropriate ultrasonic weather station sensor configuration can be selected.
