RS485 Ultrasonic Wind & Weather Sensor: 45 or 70 m/s
Use ultrasonic wind measurement where moving cups and vanes are unsuitable for the station layout. Select a 45 m/s wind or weather configuration, or a 70 m/s wind-only configuration. Temperature, humidity, pressure and optical rainfall belong to the 45 m/s weather version.
Choose the configuration
45 m/s: selected weather channels
Select temperature/RH, atmospheric pressure and optical rainfall channels. Power consumption ≤0.52 W.
70 m/s: wind only
Wind speed and direction. This range is supplied without the additional weather channels.

- The optical rainfall channel and a separate tipping-bucket rain gauge use different measurement methods.
Where it fits
Agricultural weather point
The 45 m/s version offers temperature, humidity, pressure and optical rainfall channels alongside wind on an RS485 connection.
Wind-only station
Select the 45 or 70 m/s wind range when only wind speed and direction are required.
Construction and outdoor monitoring
Provide wind readings to a site logger or monitoring system through the Modbus interface.

Questions about this equipment
Can the 70 m/s version include all weather channels?
The 70 m/s version measures wind speed and direction. The additional temperature, humidity, pressure and optical rainfall channels are available on the 45 m/s weather version.
Does the sensor have moving cups?
Wind speed and direction use ultrasonic measurement without moving cups or a mechanical wind vane.
What power is needed?
The supply range is 9–30 V. Wind-only consumption is ≤0.12 W; the weather version is ≤0.52 W.
