Product Description

The JW-XF802 series is a mini all-in-one weather station designed for projects that require multiple meteorological parameters in a compact outdoor sensor.

The series uses ultrasonic technology to measure wind speed and wind direction without conventional rotating wind cups or wind vanes. Selected configurations also integrate radar rainfall measurement together with air temperature, relative humidity, atmospheric pressure, illuminance and solar radiation.

With a maximum body dimension of approximately 83.03 × 153.30 mm, the JW-XF802 series is suitable for installations where mounting space, wiring and system integration need to be minimized.

Four configurations are available:

  • XF802: ultrasonic wind speed and wind direction
  • XF805: wind, air temperature, humidity and atmospheric pressure
  • XF806: wind, air temperature, humidity, pressure and radar rainfall
  • XF808: eight-parameter weather monitoring with illuminance and solar radiation

The weather station can be evaluated for smart agriculture, greenhouses, irrigation systems, solar PV sites, environmental monitoring, campus weather stations and distributed IoT projects.

Product Highlights

Mini Integrated Structure

The JW-XF802 series integrates multiple sensing elements into one compact enclosure.

The maximum product dimension is approximately 83.03 × 153.30 mm, making the sensor suitable for:

  • Compact monitoring poles
  • Greenhouse structures
  • Agricultural field stations
  • Small outdoor equipment cabinets
  • Solar-powered monitoring points
  • Distributed IoT installations
  • Space-limited environmental stations

The integrated structure can reduce the number of individual brackets, external sensor cables and separate installation positions required at the monitoring site.

Ultrasonic Wind Measurement

Wind speed and wind direction are measured using ultrasonic sensing technology.

The wind module supports:

  • Wind-speed range: 0–60 m/s
  • Wind-direction range: 0–359.9°
  • Wind-speed resolution: up to 0.01 m/s
  • Wind-direction resolution: up to 0.1°
  • Sampling frequency: up to 4 Hz

Because the measurement principle does not require conventional rotating wind cups or a mechanical wind vane, the sensor avoids wear associated with moving wind-measurement components.

Regular cleaning, visual inspection and data verification are still recommended for reliable long-term outdoor operation.

Radar Rainfall Measurement

The XF806 and XF808 configurations include integrated radar rainfall measurement.

The radar module detects precipitation without using the bucket-and-tipping mechanism found in a traditional tipping-bucket rain gauge.

This design is suitable for projects where the customer prioritizes:

  • Compact construction
  • Integrated installation
  • No tipping-bucket mechanism
  • Reduced mechanical components
  • Real-time rainfall intensity data
  • Multi-parameter monitoring in one device

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

Radar rainfall and tipping-bucket rainfall use different measurement principles. Customers with regulatory, hydrological or research-grade precipitation requirements should confirm the required rainfall accuracy, resolution and applicable standard before model selection.

Up to Eight Monitoring Parameters

Ultrasonic Wind Measurement

How It Works

The sensor transmits ultrasonic signals between internal transducers.

Wind changes the travel time of the signals. The instrument uses these changes to calculate wind speed and wind direction.

Unlike a conventional cup-and-vane assembly, ultrasonic wind measurement does not require rotating wind cups, bearings or a mechanical wind-direction vane.

Practical Benefits

The ultrasonic design can support:

  • Compact product dimensions
  • No wind-cup bearing wear
  • No mechanical wind-vane alignment
  • Fast response to changing wind
  • High-frequency data acquisition
  • Easier integration into a multi-parameter housing

Installation Considerations

Even a high-performance wind sensor can produce unrepresentative data when installed in a poor location.

Avoid installing the weather station:

  • Directly beside a wall
  • Below a roof edge
  • Behind a large solar panel
  • Beside an exhaust outlet
  • Under dense tree cover
  • Inside a location blocked by greenhouse structures
  • Too close to other large sensors
  • Where the mounting pole causes significant airflow interference

The sensor should be installed vertically and in an open position appropriate for the project.

Where wind-direction data is required, align the orientation mark according to the product installation instructions.

Radar Rainfall Measurement

Non-Tipping Rain Detection

The radar rainfall module measures precipitation without collecting water in a tipping-bucket mechanism.

This allows rainfall measurement to be integrated into the same compact body as the wind and meteorological sensing modules.

Suitable Applications

Radar rainfall measurement may be considered for:

  • Agricultural weather stations
  • Irrigation monitoring
  • Greenhouse external weather monitoring
  • Roadside weather nodes
  • Solar-powered stations
  • Distributed environmental monitoring
  • Campus weather stations
  • IoT monitoring projects

What Customers Should Confirm

Before selecting the radar rainfall model, confirm:

  • Required rainfall range
  • Required rainfall resolution
  • Required accuracy
  • Minimum detectable rainfall
  • Reporting interval
  • Local rainfall characteristics
  • Whether accumulated rainfall is required
  • Whether a specific meteorological standard applies
  • Whether a dedicated reference rain gauge is also required

Radar rainfall should not automatically be described as more accurate than a tipping-bucket rain gauge. The appropriate technology depends on the project objective and measurement requirement.

Recommended Applications

Smart Agriculture

The XF805, XF806 and XF808 models can provide local weather data for:

  • Field microclimate monitoring

For indoor greenhouse measurements, sensor position should be selected carefully to avoid direct irrigation spray, heating outlets, ventilation fans and localized heat sources.

Irrigation Systems

Rainfall, temperature, humidity and solar data can support irrigation planning.

The weather station can provide environmental inputs to a platform or controller, but irrigation decisions should also consider:

  • Soil moisture
  • Crop type
  • Root depth
  • Soil texture
  • Growth stage
  • Irrigation-zone conditions
  • Local evapotranspiration model

Weather data alone should not be treated as a complete irrigation-control strategy.

Solar PV Monitoring

The XF808 model includes solar radiation and illuminance measurement and may be evaluated for distributed solar or commercial rooftop projects.

Possible monitored parameters include:

  • Ambient temperature
  • Relative humidity
  • Atmospheric pressure
  • Wind speed
  • Wind direction
  • Rainfall
  • Illuminance
  • Solar radiation

For formal PV performance assessment, confirm whether the project requires a dedicated pyranometer, reference cell, plane-of-array irradiance sensor, PV module temperature sensor or soiling sensor.

The integrated solar radiation module should be selected according to the required measurement class and project specification.

Environmental Monitoring

The product can be used as the meteorological component of a broader environmental monitoring station.

It can provide weather data for interpreting:

  • Air-quality readings
  • Dust movement
  • Gas dispersion
  • Noise conditions
  • Urban microclimates
  • Industrial boundary conditions

Additional PM, gas or noise sensors normally require separate monitoring modules or an expanded station configuration.

Campus and Research Monitoring

The mini weather station can support:

  • School weather observation
  • University field projects
  • Environmental research
  • Demonstration stations
  • Experimental agriculture
  • Distributed sensor networks

Researchers should confirm calibration, data-access requirements and measurement uncertainty before selecting a model.

Smart City and IoT Nodes

The compact body can be integrated into distributed smart-city monitoring points where installation space is limited.

Possible installation locations include:

  • Smart poles
  • Public parks
  • Residential communities
  • Transport facilities
  • Roadside monitoring points
  • Municipal environmental stations

The communication method should be selected according to site power, gateway coverage, data frequency and the number of deployed stations.
