For stationary operations we further developed the innovation award-winning mobile road weather Sensor MARWIS – this is StaRWIS!

StaRWIS is the first non-invasive road weather sensor detecting road and runway surface conditions, surface temperatures, relative humidity, dew point temperatures, ice percentages as well as friction non-invasively and based on innovative LED Technology with 4 lenses.

  • Road condition (dry, moist, wet, ice, snow, slush, chemically wet), road surface temperature, water film height, dew point temperature, relative humidity, ice percentage, friction (calculated)
  • Optical LED transmitters, photo receivers, pyrometer, infrared
  • non-invasive, plug and play, 100 measurement per second, multifunctional, wireless data transfer, no moving parts
  • Bluetooth, RS485, CAN-Bus, UMB – protocol
  • 8711.U55
