Mini Compact Weather Station with Ultrasonic Wind and Radar Rainfall

The JW-XF802 Series Mini Compact Weather Station is an integrated meteorological sensor designed for space-limited outdoor monitoring, smart agriculture, environmental IoT systems, and distributed weather observation networks.

Combining ultrasonic wind measurement, optional radar rainfall detection, and up to eight weather parameters, the series provides an alternative to conventional weather stations that require multiple separate sensors and mounting brackets.

Available in four configurations—JW-XF802, JW-XF805, JW-XF806, and JW-XF808—the series supports flexible weather monitoring requirements while maintaining a compact enclosure.

1. Four Models for Different Weather Monitoring Requirements

The JW-XF802 series is available in four configurations.

JW-XF802 is suitable when an existing monitoring system requires only ultrasonic wind measurements.

JW-XF805 adds temperature, humidity, and atmospheric pressure for general outdoor weather monitoring.

JW-XF806 includes radar rainfall measurement, making it suitable for applications requiring wind and precipitation data in one compact instrument.

JW-XF808 provides the most comprehensive configuration, integrating eight meteorological parameters.

For applications requiring additional environmental parameters such as PM2.5, PM10, or noise, see the Ten-in-One Compact Weather Station.

2. Ultrasonic Wind Measurement Without Moving Parts

How Does Ultrasonic Wind Measurement Work?

The JW-XF802 series measures wind speed and direction using ultrasonic signals transmitted between sensing elements.

Changes in ultrasonic signal travel time caused by airflow are used to determine wind conditions.

Unlike mechanical cup anemometers and wind vanes, ultrasonic wind sensors do not depend on rotating bearings.

This offers several practical benefits:

• No conventional wind-cup bearing wear.
• Compact sensing structure.
• Reduced mechanical maintenance requirements.
• Wind speed and direction measurement within one sensor body.
• High-frequency sampling for observing changing wind conditions.

The series supports wind speeds up to 60 m/s, with sampling frequencies up to 4 Hz.

For applications requiring a dedicated wind sensor rather than a complete mini weather station, explore the High-Precision Ultrasonic Wind Speed and Direction Sensor.

3. Integrated Radar Rainfall Measurement

Why Choose a Radar Rainfall Weather Station?

The JW-XF806 and JW-XF808 configurations integrate radar rainfall sensing with ultrasonic wind and other meteorological parameters.

Unlike a tipping-bucket rain gauge, the radar rainfall module does not use a mechanical bucket mechanism to measure precipitation.

Its integration into the compact sensor body can reduce the need for a separately mounted rainfall instrument.

The published rainfall measurement range is 0–200 mm/h.

Radar Rainfall vs Traditional Rain Gauges

The most appropriate technology depends on measurement accuracy, rainfall characteristics, maintenance requirements, and applicable monitoring standards.

For professional hydrological rainfall monitoring, customers should also evaluate a dedicated Stainless Steel Tipping Bucket Rain Gauge.

4. Technical Specifications

The following specifications reflect the currently published JW-XF802 series information.

Technical Note: Available measurement parameters depend on the selected model. Accuracy, supply voltage, power consumption, communication interface, protection rating, and detailed installation requirements should be confirmed with the latest product datasheet.

5. Applications of the Mini Weather Station

5.1 Smart Agriculture and Irrigation Monitoring

The JW-XF806 and JW-XF808 can provide local weather data for orchards, agricultural fields, and precision irrigation systems.

Wind speed, rainfall, temperature, and humidity measurements can support irrigation planning, field microclimate analysis, and weather-related operational decisions.

For root-zone monitoring, the weather station can be integrated into a larger solution using the Soil Moisture, EC and Temperature Probe.

5.2 Greenhouse External Weather Monitoring

A compact weather station can monitor outdoor conditions affecting greenhouse operations.

Wind, rainfall, temperature, and humidity data can support greenhouse ventilation planning and external weather assessments.

For wind and rainfall measurements, the sensor should be installed outside the greenhouse in a representative, unobstructed location.

5.3 Solar PV Environmental Monitoring

The JW-XF808 integrates solar radiation, illuminance, wind, temperature, humidity, and rainfall measurements.

These parameters can support general environmental monitoring at distributed PV installations.

For performance ratio evaluation or projects requiring specified irradiance accuracy, use an appropriately classified dedicated instrument, such as the Class A Pyranometer Solar Radiation Sensor, alongside suitable module temperature measurement.

5.4 Distributed IoT Weather Networks

The series can serve as the meteorological sensing component of remote monitoring networks deployed in:

• Agricultural fields.
• Outdoor environmental monitoring points.
• Industrial facilities.
• Smart campuses.
• Solar-powered remote stations.
• Municipal monitoring locations.

System integrators can choose the model and communications equipment according to the monitored parameters, site conditions, and reporting requirements.

6. Connecting the Weather Station to IoT Platforms

The JW-XF802 series can be incorporated into a monitoring system using compatible data-acquisition equipment.

A typical architecture is:

JW-XF802 Series → Compatible Data Logger / RTU → 4G, LoRaWAN or Ethernet Gateway → Cloud Platform / SCADA

Potential functions of the larger monitoring system include:

• Remote meteorological data acquisition.
• Historical data storage.
• Weather trend visualization.
• Configurable alarms.
• Integration with irrigation or environmental control systems.
• Data exchange with customer monitoring software.

Actual compatibility depends on the selected sensor output and communication protocol.

7. Installation and Maintenance Recommendations

Correct installation is essential for obtaining representative weather data.

The station should be mounted vertically on a stable bracket or pole, following the product installation instructions.

For wind monitoring, avoid positions obstructed by buildings, large solar panels, walls, or dense vegetation.

For models with radar rainfall sensing, keep the measurement area unobstructed and inspect it periodically for dust or deposits.

Recommended maintenance includes checking mounting hardware, cables, connectors, sensor cleanliness, and data plausibility.

Although ultrasonic wind measurement eliminates conventional rotating wind cups, the complete station still requires routine inspection.
