Lufft WS200 Compact Weather Sensor

Lufft WS200 Compact Weather Sensor

The WS200 accurately measures:
  • Wind speed
  • Wind direction.
  • Serial Output – RS485 Modbus or SDI-12
  • Bird proof
  • Integrated heater
  • Ultra-sonic wind detection
  • Optional remote temperature probe


Lufft WS200 All-in-one compact weather station

The Lufft WS200 is the ideal compact weather sensor for accurately measuring wind speed and wind direction. It is suitable for high-end applications where accuracy and build quality cannot be compromised.

Using ultrasonic sensors the WS200 will simultaneously measure both wind speed and wind direction.

The WS200 is compliant with IEC 61724-1:2017 standards so quality is assured. There are no moving parts and data processing is built-in. This makes the WS200 incredibly easy to use and robust enough to withstand harsh environments.

As standard, we supply the Lufft WS200 with Modbus communications. However, it is possible to supply the sensor with SDI-12. Please let us know at the time of ordering which you would prefer.

As with all WS series compact weather sensors, it is possible to fit a temperature probe. This probe measures surface temperature and is ideal for the PV solar sector to measure the back of panel temperature.

WS Series Frequently asked questions.

How do I mount my WS sensors? 

The sensor can be mounted directly onto a 60mm diameter pole. The sensors come with ‘U’ mounting brackets. A mounting arm (which can attach to 40-80mm diameter poles) can be supplied too.

Are other communications protocols possible?

Possible interfaces are RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, XDR, and SDI-12.

What data logger is the WS200 compatible with?

The WS200 is compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol.
