Lufft MARWIS-UMB – Mobile Weather Sensor for Vehicles

Lufft MARWIS-UMB – Mobile Weather Sensor for Vehicles

Turn any vehicle into a rolling weather station. MARWIS measures road conditions, temperature and friction 100 times per second directly from your plow truck or utility vehicle. The ultimate tool for optimizing salting and proving work done in real time.

Lufft MARWIS-UMB is the market's leading mobile sensor for professional road maintenance. By mounting MARWIS on a vehicle, you receive continuous data on the condition of the road surface while you are driving. The sensor measures critical parameters such as water thickness, ice percentage, salt content and friction via infrared technology - completely without contact with the road surface.

For municipalities and contractors, MARWIS represents a paradigm shift. Instead of relying on stationary stations, you get a comprehensive picture of the entire road network. Data is transferred seamlessly via Bluetooth or RS485 to a tablet in the driver's cab or directly to the cloud. This makes it possible to make salting and plowing decisions based on actual meter-by-meter measurements, drastically reducing chemical use and increasing road safety. MARWIS is built for extreme environments and delivers reliable data even in sleet and severe cold.

Technical specifications

Measurement parameters: Road surface temperature, ambient temperature, relative humidity, dew point, road conditions (dry, humid, wet, ice, snow/ice, chemical wetness).

Friction: Calculated friction coefficient in real time.

Measurement frequency: Up to 100 measurements per second.

Installation: Simple mount for car/truck (distance to road: 1–2 meters).

Communication: Bluetooth, RS485, CAN bus.

Enclosure: IP68 – Designed to withstand salt spray and high-pressure washing.

Power supply: 10–28 VDC via the vehicle.

Installation & Commissioning

MARWIS is mounted with a robust quick-release bracket on the vehicle's towbar or specific mounting brackets.

Plug & Play: Connects via the vehicle's power outlet.

Software: Compatible with Lufft SmartView3 and mobile apps for iOS/Android.

Stormex Support: We deliver the system pre-configured for your chosen cloud platform (e.g. Sensor-Online) for immediate data visualization.

Areas of use

Winter Road Maintenance & Plowing: Give the driver real-time instructions. By seeing exactly where the freezing point is reached, the amount of salt can be adjusted as needed, saving large sums of money and protecting the environment.

Airport maintenance (Runway Monitoring): Rapid control of friction and hydroplaning risk on runways without disrupting traffic with heavy measurement carts.

Decision support for Road Managers: Use the data as evidence in claims cases or to verify that the road condition meets the contract requirements.

Research & Climate Analysis: Collect high-resolution data on thermal variations in the road network to identify local cold spots.
