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°

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
