All-in-One Ultrasonic Weather Station Sensor RS485 Modbus

The All-in-One Ultrasonic Weather Station Sensor is a configurable multi-parameter weather sensor designed to combine several meteorological and environmental measurements in one compact outdoor unit.

Five core parameters—wind speed, wind direction, air temperature, relative humidity and barometric pressure—form the basic configuration. Depending on project requirements, the sensor can also integrate rainfall, PM2.5, PM10, environmental noise and either solar radiation or illuminance, supporting configurations of up to 10 measurement parameters.

The ultrasonic weather station with RS485 Modbus can connect to compatible PLCs, weather station data loggers and IoT gateways. It is suitable for automatic weather stations, agriculture, environmental monitoring, airports, ports, transportation, research and industrial monitoring systems.

All-in-One Ultrasonic Weather Station Technical Specifications

Available Weather and Environmental Measurements

The multi-parameter ultrasonic weather sensor can be configured according to the measurements required by the project. Not every parameter listed below is necessarily included in every unit.

*Configuration note: Solar radiation and illuminance are alternative parameters and cannot both be included in the same maximum 10-parameter configuration.

Choose the Right 5-in-1 to 10-in-1 Configuration

The All-in-One Ultrasonic Weather Station family allows the sensor configuration to be matched to the actual project instead of specifying unnecessary parameters. The table below summarizes the main configurations.

The final parameter combination should be confirmed before ordering. Solar radiation and illuminance are different measurements and should not be treated as interchangeable.

How Ultrasonic Wind Measurement Works

The ultrasonic weather sensor measures wind by comparing the transit time of ultrasonic signals between opposing north-south and east-west transducers. Airflow changes the travel time of the signals in different directions, allowing wind speed and wind direction to be calculated.

This method does not require conventional rotating wind cups or a mechanical wind vane. The wind speed measurement range is 0–60 m/s with 0.01 m/s resolution.

Piezoelectric Rainfall Measurement

Configurations that include rainfall use piezoelectric ceramic kinetic detection. Raindrops striking the sensing surface generate impact signals that are processed to calculate rainfall.

The system can provide both cumulative rainfall and real-time rainfall data. Piezoelectric rainfall measurement does not use the mechanical tipping mechanism found in a traditional tipping bucket rain gauge.

PM2.5, PM10 and Noise Options

For environmental monitoring projects, the configurable weather sensor can integrate PM2.5, PM10 and environmental noise measurement together with the core meteorological parameters.

For projects requiring regulatory particulate monitoring, reference-method equivalence, traceable calibration, LAeq, Lmax, frequency weighting or other specific compliance requirements, provide the required standard before model selection.

Solar Radiation vs Illuminance vs PAR

Solar radiation, illuminance and PAR are different physical measurements. Select the measurement according to the actual monitoring purpose rather than converting one value directly into another.

RS485 Modbus RTU Integration

The multi-parameter ultrasonic weather sensor with RS485 Modbus can connect to compatible PLCs, automatic weather station data loggers and IoT gateways. A fixed Modbus data structure allows the receiving device to read the parameters included in the selected configuration.

Modbus Measurement Order

Only parameters included in the selected sensor configuration return valid measurement values. Unselected optional parameter positions are not used by that configuration.

Wiring

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

All-in-One Ultrasonic Weather Sensor Dimensions

The integrated housing has an approximate maximum diameter of 160 mm, an overall height of 286 mm and a lower mounting interface of approximately 60 mm.

Installation Recommendations

Install the ultrasonic weather sensor vertically in an open and representative monitoring location. The installation requirements depend partly on the selected parameters: wind measurement requires unobstructed airflow, rainfall measurement requires direct precipitation exposure, and solar or light measurement requires appropriate exposure without unintended shading.

Automatic Weather Station System Integration

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

The integrated sensor provides measurement data 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 weather sensor itself.

Agricultural, Environmental and Automatic Weather Station Applications

Thisautomatic weather station sensorcan be configured for basic meteorological monitoring or broader weather and environmental monitoring projects. Select the required parameters according to the application rather than specifying measurements that are not needed.

FAQ

Q1. What does an All-in-One Ultrasonic Weather Station Sensor measure?

A1. The five core measurements are wind speed, wind direction, air temperature, relative humidity and barometric pressure. Additional configurations can include rainfall, PM2.5, PM10, noise and either solar radiation or illuminance.

Q2. How many parameters can the sensor support?

A2. The configurable product family supports up to 10 measurement parameters in one integrated sensor.

Q3. Can solar radiation and illuminance be included together?

A3. No. Solar radiation and illuminance are alternative configurations. Select the one that matches the project requirement.

Q4. What is the difference between the 5-in-1 and 10-in-1 configurations?

A4. The 5-in-1 configuration provides the five core meteorological parameters. Higher-parameter configurations add measurements such as rainfall, PM2.5, PM10, noise and solar radiation or illuminance according to the selected model.

Q5. Does the ultrasonic weather station support RS485 Modbus?

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

Q6. Does the sensor itself include 4G, Wi-Fi or LoRaWAN?

A6. No. The integrated weather sensor provides RS485 data. Remote 4G, Wi-Fi, Ethernet or LoRaWAN communication requires a compatible data logger or IoT gateway.

Q7. How is wind speed and direction measured?

A7. Wind speed and direction are calculated from differences in ultrasonic signal transit time between opposing transducers, without conventional rotating wind cups or a mechanical wind vane.

Q8. How is rainfall measured in configurations that include rainfall?

A8. Rainfall is measured using piezoelectric raindrop impact detection rather than a conventional mechanical tipping bucket.

Q9. Is this a complete standalone automatic weather station?

A9. It is an integrated weather sensor. A complete remote automatic weather station normally also requires a compatible data logger or gateway, power supply, mounting system and communication method.

Q10. What information should be provided when selecting a configuration?

A10. Specify the required measurement parameters, quantity, power supply, cable length, installation environment and the PLC, data logger or IoT gateway that will receive the RS485 Modbus data. Also specify any calibration, certification or regulatory requirements.

Quotation and Configuration Selection

For quotation and configuration selection, specify exactly which parameters are required: wind speed, wind direction, temperature, humidity, pressure, rainfall, PM2.5, PM10, noise and either solar radiation or illuminance. Also provide the required quantity, power supply, cable length, installation environment and receiving PLC, data logger or IoT gateway. For projects requiring regulatory PM monitoring, specific acoustic indicators, calibration or certification, include those requirements with the inquiry.
