Lufft WS601 all-in-one compact weather station
The Lufft WS601 is ideal for measuring air temperature, relative humidity, solar irradiance, and air pressure. It is suitable for high-end applications where accuracy and build quality cannot be compromised.
The sensors are protected by a radiation shell for protection and to ensure measurement accuracy, making the WS601 compliant according to WMO guidelines.
The top-mounted precipitation tipping bucket rain gauge will accurately measure the precipitation quantity.
The WS601 is suitable for all climates, with a temperature range of -50 to +60 °C. There are no moving parts and data processing is built-in. This makes the WS601 incredibly robust and easy to use.
As standard, we supply the Lufft WS601 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. The 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 WS601 compatible with?
The WS601 is compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol.
