Visitors to Intertraffic will be the first to see the new Marwis mobile contactless weather information sensor from German company Lufft.
Marwis can be mounted on any vehicle and provides mobile collection of road weather information including surface temperature, dew point and water film height as well as road conditions (humidity, snow, ice and frost), grip (friction) and other environmental data.
The system measures meteorological data and road condition information 100 times per second at a driving speed of 80km/h, meaning the sensor records the data every 20cm.
Data from the sensors can be sent via Bluetooth for real time evaluation on a mobile device or tablet and delivered via the cloud to SmartView, Lufft’s visualisation software. According to the company, Marwis can distinguish the desired data regardless of the road surface condition - freezing ice, snow or rain.
Lufft is also exhibiting an updated in-road sensor, the IRS31Pro-UMB, which can now calculate friction and ice percentage as well as measuring temperature and road surface condition (damp, wet, icy or snow/salt).
